Campbell et al., Rev. Sci. Instrum. 57, 2101 (1986)]. The targets consist of a 5000-6000 Angstrom skin surrounding 1 atm of neopentane, which, when ionized, becomes a plasma with an electron density of 10(21) electrons/cm(3). X-ray images of the gas bag target are used to evaluate the size and uniformity of the plasma by comparison with LASNEX [R. M. More, J. Quant. Spectrosc. Radiat. Transfer 27, 345 (1982)] simulations. The gas bags are heated with converging and diverging beam spots. The most uniform plasmas are created by illuminating the target with large converging beam spots that overlap to cover most of the surface of the gas bag. The gas bag plasma is heated to a peak temperature of approximately 3.5 keV, with 25 kJ of 3 omega laser light in a 1 ns square pulse. (C) 1995 American Institute of Physics.

The ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) content declined by 45% in the control leaves, but by 60% in the leaves grown at the elevated CO2 concentration, The light- harvesting complex of photosystem II (LHCII) and the chlorophyll content showed no decrease and no difference between treatments, indicating that the decrease in Rubisco was not an effect of earlier senescence in the leaves at the elevated CO2 concentration. Following completion of the emergence of the flag-leaf blade, the elevated-CO2 treatment inhibited the further accumulation of Rubisco which was apparent in control leaves over the subsequent 14 d, From this point onwards, the flag leaves from both treatments showed a loss of Rubisco, which was far more pronounced in the elevated-CO2 treatment, so that by 36 d the Rubisco content of these leaves was just 70% of that of the controls and by 52 d it was only 20%, At 36 d, there was no decline in chlorophyll, LHCII or the chloroplast ATPase coupling factor (CFI) in the elevated CO2 concentration treatment relative to the control, By 52 d, all of these proteins showed a significant decline relative to the control, This indicates that the decreased concentration of Rubisco at this final stage probably reflected earlier senescence in the elevated-CO2 treatment, but that this was preceded by a CO2-concentration-dependent decline in Rubisco.

Loida (1994, PhD Thesis, University of Illinois at Urbana-Champaign, IL) and S.G.Sligar (personal communication) have observed recently that an active-site variant of cytochrome P450cam (F87W) dechlorinates pentachloroethane approximately three times faster than the wild-type enzyme, Molecular dynamics simulations have revealed that the mutant enzyme binding pocket remains smaller, and that pentachloroethane assumes configurations closer to the heme-Fe in the F87W mutant twice as often as in the wild-type enzyme, This result is consistent with a collisional model of dehalogenation, which agrees with experimental observations[li and Wackett (1993) Biochemistry, 32, 9355-9361] that solutions containing wild-type P450cam dehalogenate pentachloroethane 100 times faster than those containing free heme, The simulations suggest that it is unlikely that Trp87 significantly stabilizes the developing negative charge on the substrate during carbon-halogen bond reduction, The design of improved microbial enzymes that incorporate both steric and electronic effects continues for use in remediating halogenated contaminants in situ.

Mitogenic or growth inhibitory signals are mediated, respectively, by activation or inhibition of CDKs which phosphorylate proteins associated with the cell cycle. The central role of CDKs in cell cycle regulation makes them a potential new target for inhibitory molecules with anti-proliferative and/or anti-neoplastic effects. We describe the crystal structures of the complexes of CDK2 with a weakly specific CDK inhibitor, N6-(Delta(2)-isopentenyl)adenine, and a strongly specific inhibitor, olomoucine. Both inhibitors are adenine derivatives and bind in the adenine binding pocket of CDK2, but in an unexpected and different orientation from the adenine of the authentic ligand ATP. The N6-benzyl substituent in olomoucine binds outside the conserved binding pocket and is most likely responsible for its specificity. The structural information from the CDK2-olomoucine complex will be useful in directing the search for the next generation inhibitors with improved properties. (C) 1995 Wiley-Liss, Inc.

There are gains in performance as well as efficiency: stellar photometry is more straightforward because of the higher dynamic range of CCDs, and the low noise of CCDs allows narrow-band surveys to be undertaken. The small dead-time between exposures allows surveys for rapid variability as well as near-simultaneous color measurements. The most important new prospect may be real-time analysis for identification of sources changing either in position or in brightness. These gains come only after substantial investment in analysis tools and data handling and storage systems. To illustrate some of this potential, this review will focus on a number of sky surveys with CCDs that are either under way or in advanced implementation stages.

In general SI is well suited for application to atmospheric chemistry; specifically the wide range of magnitudes that are encountered can be dealt with by the prefixes denoting multiples and submultiples of units, and the application of SI units leads automatically to consistency in unit calculus. The use of special names and symbols for units that are not part of the SI, and are not products of powers of SI base units is discouraged; examples are atmosphere, Dobson unit, hectare. However, continued use of such units (especially the Dobson unit) alongside SI units is advisable for a time until the SI units become more familiar. Local abundances of substances in air may be expressed as mixing ratios or concentrations. Mixing ratio has the advantage of being independent of pressure or temperature, but concentration has advantages for reaction kinetics and material transport. Amount-based units for mixing ratios or concentrations of substances of known chemical composition are preferable to mass-based units. The dimensionless unit mol per mol of air is recommended for mixing ratio of a substance in air, e.g. nmol/mol, rather than the customary parts per billion (ppb). It is necessary to specify whether a mixing ratio refers to dry or moist air. Expressing mixing ratios as ''reduced concentrations'' relative to standard conditions of pressure and temperature leads to ambiguity and should be avoided where possible. Gas-phase concentrations may be expressed on the basis of either mole (mol m(-3)) or molecule (molecule m(-3); SI: m(-3)). The universal use of a single set of units for gas-phase concentration does not seem forthcoming in the immediate future, although the use of mol(-3) affords advantages of consistency and convenience. An extensive table of m recommended symbols and SI units for quantities in atmospheric chemistry is presented. C1 MAX PLANCK INST CHEM,BIOGEOCHEM ABT,D-55020 MAINZ,GERMANY.

This work has revealed many gaps in our knowledge that require further study. Despite investigations of several irradiated populations, the atomic-bomb survivors remain the primary basis for estimating the risk of ionizing radiation. Compared with previous estimates, two new independent evaluations of available information indicate a significantly greater risk of stochastic effects of radiation (cancer and genetic effects) by about a factor of three for radiation workers, including space travelers. This paper presents a brief historical perspective of the international effort to assure radiation protection in space. C1 OAK RIDGE NATL LAB,DIV BIOL,OAK RIDGE,TN 37830.

Two recent developments have greatly advanced the practical aspects of implementation of these methods, The first was the formulation of a closed-form solution as a multiple fragmentation perturbation series, The second was the effective summation of the closed-form solution through nonperturbative techniques, The nonperturbative methods have been recently extended to an inhomogeneous, two-layer transport media to simulate the lead scattering foil present in the Lawrence Berkeley Laboratories (LBL) biomedical beam line used for cancer therapy. Such inhomogeneous codes are necessary for astronaut shielding in space. The transport codes utilize the Langley Research Center atomic and nuclear database. Transport code and database evaluation are performed by comparison with experiments performed at the LBL Bevalac facility using 670 A MeV Ne-20 and 600 A MeV Fe-56 ion beams. The comparison with a time-of-flight and Delta E detector measurement for the Ne-20 beam and the plastic nuclear track detectors for Fe-56 show agreement up to 35%-40% in water and aluminium targets, respectively.

The yield of DNA strand breaks is determined by the agarose gel electrophoresis method. High-performance liquid chromatography (HPLC) is used to assay the release of unaltered nucleic bases. Previously reported HPLC methods have been updated. Unaltered base release is linear with dose up to 424 Gy, where up to 0.2% of all DNA bases are released. No detectable amounts of unaltered nucleosides are released and, besides unaltered bases, only one other product released from DNA is observed. Base release yields do not reflect the PM2 GC content of 43%. Only 76% of all prompt strand breaks appear to be associated with the release of an unaltered free base, whereby the guanine, cytosine, adenine and thymine yields are 9, 27, 18 and 22% of the prompt strand break yield, respectively. Postirradiation incubation at 37 degrees C for 24 h increases the strand break yield 1.38-fold and the unaltered base release yield 1.76-fold such that 97% of the final strand breaks appear to be associated with the release of an unaltered base, whereby the guanine, cytosine, adenine and thymine yields are 10, 36, 23 and 28% of the final strand break yield, respectively. These data indicate that, given proper conditions, nearly every strand break leads to a base release. The bearing of these results on OH radical attack leading to strand breakage and base release is discussed.

Toxicol. Pharmacol. 9, 101-108, 1989) showed that the regulatory virtually safe dose (VSD), corresponding to an estimated lifetime cancer risk of less than 10(-6), could be estimated within a factor of 10 simply by dividing the maximum tolerated dose (MTD), estimated from the results of a 90-day study, by 380,000. The purpose of this current study was to extend the analysis to all carcinogens in the Carcinogenic Potency Database (CPDB) utilizing the TD50 (average daily dose rate in mg/kg body wt/day that was estimated to halve the probability of remaining tumor-free at a specified tissue site throughout a a-year study). Using the relationship between the upper bound on the low-dose slope (q(1)*) and the TD50 reported by Krewski et al. (Risk. Anal. 13, 383-398, 1993) and the ratio of the maximum dose tested (Max-D)/TD50 obtained in our present analysis, an estimate of the regulatory VSD was given by the MTD/740,000, for NCI/NTP rodent carcinogens. This was about a factor of two lower than the limited analysis conducted by Gaylor. There was little difference when the chemicals were divided into mutagens and nonmutagens. Ninety-six percent (134 of the 139 NCI/NTP rodent carcinogens) of the regulatory VSDs calculated from the individual TD(50)s obtained from the 2-year bioassays were within a factor of 10 of the MTD/740,000. Gold et al. (Environ. Health Perspect. 79, 259-272, 1989) investigated the distribution of the TD50 among ''near-replicate'' experiments (where the same chemical was tested more than once and was positive in the same strain, sex, and species by the same route). The distribution of TD(50)s from near-replicate experiments is similar to the distribution of the Max-D/TD50. Hence, the estimate of the regulatory VSD based on the Max-D/740,000, for NCI/NTP bioassays, is about as precise as the estimate obtained from a 2-year bioassay. This questions the advisability of conducting a 2-year bioassay for purposes of regulatory risk estimation. Since resources are available to test only a small fraction of chemicals to which humans are exposed, a preliminary estimate of the regulatory VSD can be useful in setting testing priorities. If the expected human exposure level is below the regulatory VSD estimated from the MTD, a chemical may be assigned low priority for testing in a 2-year bioassay. Based on previous work the FDA proposed a ''threshold of regulation'' of a dietary concentration of 0.5 ppb for all substances used in food-contact articles. The results of the present analysis could be used to make the procedure more chemical specific based upon an available MTD. The high correlation between the MTD and estimate of cancer potency (TD50) can be exploited to provide a preliminary, hypothetical upper bound estimate of cancer risk for exposure to a chemical without conducting a 2-year animal bioassay. Thus, the expected level of human exposure relative to the MTD can be used to determine the priority for further research on a chemical, such as mechanistic studies. (C) 1995 Academic Press, Inc.

These techniques routinely provide detail and precision that are difficult to achieve in single-photon ionization from the ground state. The review not only emphasizes new aspects of photoionization revealed in the excited-state experiments but also shows how the excited-state techniques can provide textbook illustrations of some fundamental mechanisms in molecular photoionization dynamics. Most of the examples are confined to diatomic molecules. RP ARGONNE NATL LAB, 9700 S CASS AVE, ARGONNE, IL 60439 USA.

First, we estimate production functions for six activities on multiproduct farms, finding evidence of increasing returns to scale in cattle activity and possible evidence of nonindependence of profit and utility maximization in several subsistence crops. Second, we examine determinants of overall current farm revenue and wealth, finding possible evidence of overuse of land and underinvestment in cattle, decapitalization of farms over time, overpopulation, and a trade-off between children and capital accumulation. Third, we study interactions between burning strategies, diversification: of farm activities, locational choice, length of tenure on a farm, and soil quality. Longer tenure on a farm and larger area in perennial crops appear to reduce the frequency of burning, while greater area in annual crops increases the frequency. Larger pasture area tends to reduce the frequency of burning below an annual periodicity. Less frequent burning appears to be accompanied by greater diversification of farm income sources. Fourth, we study the determinants of deforestation on lots, finding a negative effect of clearance costs study and productivity of land in cultivation on the clearance of new land. However, the evidence for the relationship between cattle activity and deforestation is mixed: a larger number of cattle increases the absolute amount of land deforested on a lot, but a higher proportion of income from cattle increases the ratio of cultivated land to pasture on a farm. There is also evidence of a trade-off between land quality and the quantity of land deforested. C1 OAK RIDGE NATL LAB,DIV ENVIRONM SCI,OAK RIDGE,TN 37831.

Third-generation synchrotron facilities with their inherent high brightness have the unique potential to cover this energy region with high-resolution, high-flux x-ray beams ideal for spectroscopic studies. A 5.5-cm-period, planar undulator to be installed on the 7-GeV Advanced Photon Source will produce a high brightness source of intermediate-energy x rays. The 0.5- to 3-keV spectroscopy beamline is based on the spherical grating monochromator design that has already been shown to yield high resolution and throughput in the soft-x-ray region, below 1 keV. The beamline has been designed to cover the entire region with a peak resolving power of 6000-10 000. Photon flux at the sample is calculated to be in the range from 10(11) to 10(13) photons/s into a spot size of 1 mm(2). A refocusing mirror will be used to further demagnify the image size at a second experimental station. As a second phase to the spectroscopy program, an elliptically polarized insertion device will be used. The polarization preserving nature of the grazing incidence optical elements in the SGM is crucial to obtain x rays of well-defined polarization. The beamline layout, together with calculations of resolution, throughput, power loading, and high harmonic suppression, will be presented. The photoemission experimental end stations for the spectroscopy station will also be briefly described. (C) 1995 American Institute of Physics.

Production of high charge state ions was increased a factor of 2-5 or higher for the very heavy ions such as bismuth and uranium, as compared to single-frequency heating. Plasma stability was improved and the ion charge state distribution shifted to higher charge state. With two-frequency heating, the source can produce more than 1X10(9) pps of fully stripped argon. High charge state ion beams of bismuth and uranium produced by the source were injected into the 88-Inch Cyclotron at LBL. After acceleration to energies greater than 6 MeV/nucleon, the extracted beam intensities were 1X10(6) pps or higher for Bi-50+,Bi-51+ and U-238(52+,53+). (C) 1995 American Institute of Physics.

The linear temperature measurement range extends from <1 degrees to approximately 15,000 degrees C relative to ambient with a simultaneous capability to monitor surface reflectivity with the local oscillator leakage. Reliable and robust operation on a continuous 24 h basis in a smoky, dirty furnace environment is demonstrated for a total of five furnace runs reaching a maximum temperature of 2200 degrees C. Complete temperature profile measurements with approximately 5 cm spatial resolution clearly documented thermal gradients on the slag melt surface and refractory walls and ceiling for all operating regimes of the furnace. The unique active probing capability of this instrument provided additional real-time information on melt surface turbulence, changing furnace wall emissivity, and millimeter-wave optic losses inside the furnace.

The vortex line energy in the anisotropic London model can be solved by Fourier transformation, but the core cutoff is not present in the model. Using the Klemm-Clem transformations of the free energy and vortex coordinates in the anisotropic Ginzburg-Landau model, a theorem relating the shape of the effective core cross-section in the anisotropic London model to that in the anisotropic Ginzburg-Landau model is presented. This theorem allows the anisotropic London model to be used in the entire regime H-c1 less than or equal to H much less than H-c2, regardless of the anisotropy and field direction. The resulting lower critical field H-c1(theta(H)) can exhibit a discontinuity, a kink, or be monotonic in its angular dependence. In addition, the transformations are applied to the case of a core cross-section of a single Vortex in the Lawrence-Doniach model, and the angular dependence of the magnetic torque is calculated. The torque exhibits the expected dimensional crossover, having an angular dependence which reduces to that for an anisotropic Ginzburg-Landau superconductor very near to T-c, and to that for a lattice of coupled, parallel Josephson junctions well below the dimensional crossover temperature T*. In the vicinity of T*, however, dramatic oscillations in the angular dependence of the torque are predicted.

Steric hindrance between adjacent substituents positions the pi system of the chlorophyll perpendicular to that of the porphyrin. In turn, the pi system of the chlorophyll is held about 60 degrees to that of the O-O axis of the quinones in 1 and 2, parallel to the quinone O-O axis in 3, and parallel to the N-N axis in the diimide acceptor in 4. The resulting structures place the ZC donors in 1, 2, 3 and 4 at fixed center-to-center distances of 20, 18, 14, and 21 Angstrom from the accepters, respectively. Photoexcitation of 1-4 in 2-methyltetrahydrofuran glass at 77K results in a single observable electron transfer reaction: (1*)ZC-ZP-X --> ZC(+)-ZP-X(-), where X = benzoquinone (BQ), naphthoquinone (NQ) or naphthalenediimide (NI), that occurs with tau = 4.5, 3.3, 2.0, and 2.0 ps for 1, 2, 3, and 4, respectively. The final ZC(+)-ZP-X(-) radical pairs live for 12.7, 8.4, 2.5, and 10 ms at 77K in 1, 2, 3, and 4, respectively, and exhibit spin-polarized EPR spectra characteristic of spin-correlated radical pairs. The EPR spectra of 1-4 can be simulated using the distances and orientations of the radicals relative to one another determined from the molecular structures of 1-4. These long-lived, spin-polarized radical ion pairs closely mimic the bacteriochlorophyll cation - quinone anion radical pair produced in photosynthetic reaction centers and provide a useful tool for studying the interaction of the surrounding medium with the charge separated radical ion pair.

For a polarizability given by the Lindhard or the Penn model, any local density approximation, e.g. Kohn-Sham exchange and Ceperley-Alder correlation, violates the stability constraint for k(F)-values smaller than a maximum value. At least one microscopic calculation of the dielectric function also violates the stability criterion for small k(F)-values. This violation does not occur for non-local density functionals with an exponentially or Gaussian-screened Coulomb interaction. C1 LOS ALAMOS NATL LAB, DIV THEORET, LOS ALAMOS, NM 87545 USA.

This enabled the elimination of possible disturbances due to stray magnetic fields. Corresponding theoretical I-V curves have been obtained in good agreement with experimental data when an image-type surface barrier and anisotropy of the electron attenuation were taken into account. The reliability factor analysis indicates a slight expansion of the topmost interatomic spacing of Cu(111) relative to its bulk value.

Zn atoms supported on clean Mo(110) desorb at 670 (first layer), 510 (second layer) and 480 K (multilayer). The Mo-Zn bond is considerably stronger (similar to 10 kcal/mol) than the Zn-Zn bond. The strong Mo <--> Zn interaction leads to shifts of similar to 0.35 eV toward lower binding energy in the Zn 3d and 2p levels, and in the ZnL(3)M(45)M(45) Auger transition. At submonolayer coverages (theta(S) + theta(Zn) < 1 ML), Zn and S adatoms do not react to form zinc sulfides on top of Mo(110). The Zn and S adatoms compete for making bonds with the Mo(110) substrate. This competition produces a significant (5-10 kcal/mol) weakening in the strength of the Mo-Zn bond. Surfaces with submonolayer coverages of Zn and S show desorption of Zn at temperatures between 450 and 650 K, with S still remaining on the surfaces at 1200 K. The exposure of Zn/Mo(110) surfaces to large amounts of S-2 gas (theta(S) > 1 ML) at 300 K produces zinc sulfides and chemisorbed sulfur, without forming molybdenum sulfides. At 600-700 K, zinc promotes the formation of molybdenum sulfides by favoring the migration of sulfur from the surface into the lattice of the Mo substrate. In the ZnxS/MoyS/Mo(110) systems, the zinc sulfides decompose from 750-950 K, whereas the molybdenum sulfides dissociate at much higher temperatures (1200-1350 K).

For Al films of average thickness similar to 15 Angstrom deposited at 300 K, LEIS demonstrates that the Ru substrate is completely covered. Upon annealing to similar to 1000 K LEIS shows the reappearance of Ru at the surface. At the same time, the metallic Al2p peak shifts to lower binding energy and a low binding energy shoulder appears on the Ru3d peak, suggesting Al/Ru interfacial alloying. Annealing Al films to similar to 1000 K in 1 X 10(-4) Torr oxygen produces an oxidized surface layer that completely covers the Ru substrate; the resultant aluminum oxide films are stoichiometric.

We have found that lattice step atoms start to move along the [110] steps around 400 K. In thermal equilibrium, the top surface layer becomes a square with its four sides parallel to the [110] directions. At higher temperatures (500 K or higher), step atoms start to dissociate from edge sites, kink sites, ledge sites and other sites randomly so that one-dimensional step roughening occurs. By measuring the mean square deviation of the step heights at various temperatures, the kink energy for the Ir(001) steps can be derived to be 1.36 eV. C1 ACAD SINICA,INST PHYS,TAIPEI 11529,TAIWAN.

The contaminant concentration, as a function of location in the tube and time after Bushing begins, is classically modeled as the solution of a linear second-order partial differential equation. Here, we consider the related issues of how contaminant concentration measured at some location-time combinations can be used to approximate concentration at other locations and times and how the sampled location-time combinations can be most effectively selected for this purpose (i.e., experimental design). The method is demonstrated for the case in which initial concentrations are approximated based on data collected only at the downstream end of the tube. Finally, the effect of misspecifying one of the model parameters is discussed, and alternative designs are developed for instances in which that parameter must be estimated from the data.

The VCM faults are often considered to be remnants of the original subduction zone, but recent work indicates that many have undergone substantial postsubduction reactivation. In the Orocopia Mountains, for example, the Orocopia Schist exhibits an exceptionally complex structural and metamorphic history due to multiple periods of movement along the Orocopia fault. Structures in the schist include isoclinal folds with axial-planar schistosity, open-to-tight folds that fold schistosity, penetrative stretching lineations, and crenulation lineations, all of which show a nearly 360 degrees range in trend. Folds and lineations that trend approximately NE-SW occur throughout the schist and are thought to be part of an early phase of deformation related to subduction. Folds of this orientation show no consistent vergence. Folds and lineations that trend approximately NW-SE are concentrated near the Orocopia fault and are interpreted to have formed during exhumation of the schist. The NW-SE trending folds, and shear indicators in late-stage mylonite at the top of the schist, consistently verge NE. The exhumation event culminated in emplacement of the schist against brittlely deformed upper plate. Exhumation of the Orocopia Schist was accompanied by retrograde replacement of garnet, biotite, epidote, and calcic amphibole by chlorite, calcite, and sericite. Matrix amphibole has a lower Na/Al ratio than amphibole inclusions in albite, consistent with a late-stage decrease in pressure. As NE vergence in the Orocopia Mountains is associated with exhumation of the schist, the NE movement along other segments of the VCM fault may also be late and therefore have no bearing on the facing direction of the VCM subduction zone, contrary to past interpretations.

This treatment caused cell proliferation to be temporarily arrested, after which the cells spontaneously resumed cell proliferation in a radiomimetic manner. Immediately following treatment, it was found that sodium arsenite affected only mitotic-specific H1 and H3 phosphorylations. Neither interphase, nor mitotic, H2A and H4 phosphorylations were affected, nor was interphase H1 phosphorylation affected. The phosphorylation of H1 was inhibited only in mitosis, reducing H1 phosphorylation to 38.1% of control levels, which was the level of interphase H1 phosphorylation. The phosphorylation of both H3 variants was inhibited in mitosis, the less hydrophobic H3 to 19% and the more hydrophobic H3 to 24% of control levels. These results suggest that sodium arsenite may inhibit cell proliferation by interfering with the cyclin B/p34(cdc2) histone kinase activity which is thought to play a key role in regulating the cell cycle. It has been proposed that H1 and H3 phosphorylations play a role in restructuring interphase chromatin into metaphase chromosomes. Interference in this process by sodium arsenite may lead to structurally damaged chromosomes, resulting in the increased cancer risks known to be produced by arsenic exposure from the environment.

We evaluated the effectiveness of an unlipidated recombinant OspA as a vaccine in hamsters. This molecule is soluble and can be produced in high yield in Escherichia coli, characteristics that permit simple and relatively low cost production Vaccination with unlipidated OspA protected a substantial portion of animals-59-79%, depending on the challenge strain and route-against moderate doses of spirochetes delivered either by injection or by bite of infected nymphal ticks (Ixodes scapularis), The instances of vaccine failure were associated with development of low levels of antibody to a particular OspA epitope, one defined by mAb LA-2. At least 50 ng ml(-1) of LA-2 equivalent antibody was necessary for protection of hamsters. Lower LA-2 equivalent antibody concentrations occurred in unprotected animals in the presence of high-titered polyclonal antibody to native OspA. A competitive binding assay to quantitate this serum fraction is described that should be of use in monitoring the quality of the antibody response to OspA in vaccine trials. Concentrations of LA-2 equivalent antibody parallel the ability of the serum specimens to inhibit the growth of B. burgdorferi in culture. C1 BROOKHAVEN NATL LAB,DEPT BIOL,UPTON,NY 11973.

Circularly-polarized X-rays produce spin-polarized photoelectrons from the Fe 2p doublet, and intensity asymmetries in the 2p, level are observed. Fully spin-specific multiple scattering calculations reproduce the experimentally-determined energy and angular dependences.

Vegetation richness and vegetation clustering showed a scare-dependent relationship to elevation across the range of quadrat sizes from 500 to 50,000 mi(2). All diversity measures increased east to west, with a rather abrupt transition at the Colorado Front Range. The longitudinal diversity gradients found in this study are in contrast to the reported latitudinal and longitudinal gradients for species diversity. C1 DESERT RES INST,CTR BIOL SCI,RENO,NV 89512.

Such transformations are closely tied to local geochemical conditions. Favorable degradation pathways depend upon local redox conditions through thermodynamic constraints and the availability of appropriate mediating microbial populations. Conversely, the progress of the degradation reactions may affect the chemical composition of groundwater through changes in electron donor/acceptor speciation and pH, possibly inducing mineral precipitation/dissolution reactions. Transport of reactive organic and inorganic aqueous species through open systems may enhance the reaction process by mixing unlike waters and producing a state of general thermodynamic disequilibrium. In this study, field data from an aquifer contaminated by petroleum hydrocarbons have been analyzed using a mathematical model which dynamically couples equilibrium geochemistry of inorganic constituents, kinetically dominated sequential degradation of organic compounds, and advective-dispersive chemical transport. Simulation results indicate that coupled geochemical processes inferred from field data, such as organic biodegradation, iron reduction and dissolution, and methanogenesis, can be successfully modeled using a partial-redox-disequilibrium approach. The results of this study also suggest how the modeling approach can be used to study system sensitivity to various physical and chemical parameters, such as the effect of dispersion on the position of chemical fronts and the impact of alternative buffering mineral phases (e.g., goethite versus amorphous Fe(OH)(3)) on water chemistry.

Article ID LUND MONTE-CARLO; JET FRAGMENTATION; E+E-PHYSICS; DELPHI; DECAYS AB A measurement of B meson lifetimes is presented using data collected from 1991 to 1993 by the DELPHI detector at the LEP collider, Samples of events with a D meson and a lepton in the same jet are selected where ($) over bar D(0)l(+) and D*(-)l(+) events originate mainly from the semileptonic decays of B+ and B-0 mesons, respectively. From the reconstructed B decay length and the estimated B momentum, taking into account the dilution due to B decays into ($) over bar D**l(+)v, the following B meson lifetimes and lifetime ratio are measured: tau(B+) = 1.61(-0.16)(+0.16) (stat.) +/- 0.12 (syst.) ps tau(B-0) = 1.61(-0.13)(+0.14) (stat.) +/- 0.08 (syst.) ps tau (B+)/tau(B-0) = 1.00(-0.15)(+0.17) (stat.) +/- 0.10 (syst.) and an average lifetime of B+ and B-0 mesons is obtained: tau(B) = 1.61(-0.07)(+0.08) (stat.) +/- 0.05 (syst.) ps C1 IOWA STATE UNIV SCI & TECHNOL,AMES LAB,AMES,IA 50011.

ANNIHILATION; PARTON DISTRIBUTIONS; POMERON STRUCTURE; HIGH-ENERGY; ZEUS; CALORIMETER; JET; FRAGMENTATION; SUPPRESSION AB This paper presents measurements of K-0 and Lambda production in neutral current, deep inelastic scattering of 26.7 GeV electrons and 820 GeV protons in the kinematic range 10 < Q(2) < 640 GeV2, 0.0003 < x < 0.01, and y > 0.04. Average multiplicities for K-0 and Lambda production are determined for transverse momenta p(T) > 0.5 GeV and pseudorapidities \eta\ < 1.3. The multiplicities favour a stronger strange to light quark suppression in the fragmentation chain than found in e(+)e(-) experiments. The production properties of K-0's in events with and without a large rapidity gap with respect to the proton direction are compared. The ratio of neutral K-0's to charged particles per event in the measured kinematic range is, within the present statistics, the same in both samples. C1 UNIV BOLOGNA, I-40126 BOLOGNA, ITALY.

For both electron and muon pairs the low-mass spectrum can be explained satisfactorily by lepton pairs from hadronic decays, and there is no need to invoke any ''unconventional'' source. The normalisation of the major hadronic sources is set by the data. The upper limit, at 90% confidence level, on any new source of lepton pairs is similar to 20% of the hadronic decay contribution for muons, and similar to 40% for electrons.

Subtle effects are demonstrated after reduction of the between-animal variability by normalization to corpus striatum. Substantial in vivo m2-selectivity is exhibited by QNB and DIBD, modest in vivo m2-selectivity is exhibited by E-(+, +)-IQNP, and little or no in vivo m2-selectivity is exhibited by PBID and E-(+, -)-IQNP. Surprisingly, the in vive m2-selectivity is not correlated with the in vitro m2selectivity. For example, QNB, which appears to be the most strongly in vivo m2-selective compound, exhibits negligible in vitro m2-selectivity. These examples indicate that a strategy which includes only preliminary in vitro screening may very well preclude the discovery of a novel compound which would prove useful in vivo.

This system should exhibit a range of phenomena, including phase locking, modulation, frequency shifts, and energy and momentum exchange. When two or more gyrators are mutually commensurate (the ratio of their frequencies can be expressed with integers), a strong, resonant interaction is possible. Under some conditions the system is chaotic, exhibiting a strong dependence on initial conditions and poor repeatability. This paper treats all of the above effects with the aid of numerical simulation of the motion of interacting charge clouds. These phenomena are collectively known as ''space-charge'' effects and can limit the performance of Fourier transform ion cyclotron resonance mass spectrometers.

The addition of tritium ions to a deuterium plasma allows for absorption of the rf waves at the tritium cyclotron harmonics and by electron damping of a mode converted ion Bernstein wave. Competing mechanisms include direct electron damping and damping at the fundamental cyclotron resonance of deuterium, alpha particles, and He-3 ions. The contribution of each is estimated from a series of plasma discharges where various plasma parameters are varied. The majority of the rf power is found to damp on the tritium ions.

The pellet charge exchange technique shows the fusion generated alpha's in the core of the Tokamak Fusion Test Reactor plasma slow down classically, and appear to be well confined. Preliminary indications are that stochastic ripple effects are responsible for steepening the energy distribution outside the plasma core (r/a greater than or similar to 0.35).

Fluid Mech., 78, 49-63 (1976)) and others have described artificial compressibility iteration schemes for solving implicit time discretizations of the unsteady incompressible Navier-Stokes equations. Such schemes solve the implicit equations by introducing derivatives with respect to a pseudo-time variable tau and marching out to a steady state in tau. The pseudo-time evolution equation for the pressure p takes the form partial derivative p/partial derivative tau = -a(2) del . u, where a is an artificial compressibility parameter and u is the fluid velocity vector. We present a new scheme of this type in which convergence is accelerated by a new procedure for setting a and by introducing an artificial bulk viscosity b into the momentum equation. This scheme is used to solve the non-linear equations resulting from a fully implicit time differencing scheme for unsteady incompressible flow. We find that the best values of a and b are generally quite different from those in the analogous scheme for steady flow (J. D. Ramshaw and V. A. Mousseau, Comput. Fluids, 18, 361-367 (1990)), owing to the previously unrecognized fact that the character of the system is profoundly altered by the presence of the physical time derivative terms. In particular, a Fourier dispersion analysis shows that a no longer has the significance of a wave speed for finite values of the physical time step Delta t. Indeed, if one sets a similar to \u\ as usual, the artificial sound waves cease to exist when Delta t is small and this adversely affects the iteration convergence rate. Approximate analytical expressions for a and b are proposed and the benefits of their use relative to the conventional values a similar to \u\ and b = 0 are illustrated in simple test calculations.

In each case, except P alpha MS, the materials were saturated to > 99% conversion with no chain degradation. PS hydrogenations required the addition of small amounts of tetrahydrofuran to the reaction solvent cyclohexane to enhance miscibility and eliminate large-scale chain degradation. Density gradient and differential scanning calorimetry (DSC) measurements were used to characterize the density and glass transition temperature, T-g, of the unsaturated and saturated polymers. Saturation reduces the density by 3% to 11% and changes T-g substantially. The greatest variation in T-g is obtained with the 3-methyl substituted species where a 63 degrees C increase is observed, while the highest measured T-g is 186 degrees C for P2MVCH. Small-angle neutron scattering (SANS) experiments on binary mixtures of hydrogenous and deuterium labeled PVCH derivatives provided a determination of bulk chain statistics. The statistical segment length is relatively insensitive to vinylcyclohexane ring substitution, except with P3MVCH where a 20% greater value is obtained. (C) 1995 John Wiley & Sons, Inc.

A closed-form analytical expression of the shock layer is obtained for a parabolic isotherm. This solution depends on a dimensionless number which may be used to characterize the degree of nonlinear behavior of the band profiles and to select the model most appropriate for their accurate description. The profiles resulting from this solution are compared with those obtained by numerical calculations under different conditions to assess the influence of the assumptions made. The differences observed illustrate the sensitivity of the elution profiles to small changes in the equilibrium isotherm. C1 OAK RIDGE NATL LAB,DIV CHEM & ANALYT SCI,OAK RIDGE,TN 37831.

Cooperative effects at an organic-inorganic interface resulted in similar co-alignment of calcite at polymeric Langmuir-Schaefer films of 10,12-pentacosadiynoic acid (p-PDA). The films nucleated calcite at the (012) face, and the crystals were co-aligned with respect to the polymer's conjugated backbone. At the same time, the p-PDA alkyl side chains reorganized to optimize the stereochemical fit to the calcite structure, as visualized by changes in the optical spectrum of the polymer. These results indicate the kinds of interactions that may occur in biological systems where large arrays of crystals are co-aligned.

The excitation laser flux is maintained at low levels (<2 MW/cm(2)) to obtain product distributions free of secondary interactions following fragment ejection from the crystal surface. At low fluence, the NO photodesorption yield is found to be linear with desorption laser power indicating that single-photon absorption events lead to fragment ejection. The desorption yield is enhanced by roughly a factor of 1000 for resonant excitation (213 nm) over nonresonant excitation (266 nm) on a per-photon basis. We determine the relative vibrational, rotational, and translational energy distributions of the neutral NO photoproducts. Significant population in vibrational levels up to upsilon('') = 4 is observed and translational distributions for the upsilon('') = 0-3 levels are determined. Rotational state populations and translational energy distributions are well characterized by thermal distributions at the substrate temperature. A local excitation mechanism for NO desorption following resonant excitation is proposed. Under these experimetnal conditions the resonant desorption process (213 nm) is dominated by the photochemistry of the surface nitrate ions. A model for the absorption/dissociation mechanism is proposed that differs from that reported for gas phase ions in that it accounts for the stabilization of the ions due to the crystalline field. The role of exciton migration following resonant excitation is also discussed. C1 PACIFIC NW LAB, ENVIRONM MOLEC SCI LAB, RICHLAND, WA 99352 USA. OPT COATINGS LAB INC, SANTA ROSA, CA 95407 USA.

Two rotational cascades exhibiting characteristic superdeformed behaviour have been observed in Sr-82, Cranked Woods-Saxon calculations have been performed and these suggest that both bands have the, v5(2) pi 5(1) intrinsic intruder configuration and that they differ in the signature component of the [431]1/2 proton orbital which is occupied.

In supergravity models, such a source of supersymmetry breaking typically makes a contribution to scalar masses of order m(-2) similar to H-2, where H-2 similar to V/M(p)(2) is the Hubble parameter during inflation. We show that in supergravity models which possess a Heisenberg symmetry, supersymmetry breaking makes no contribution to scalar masses, leaving supersymmetric flat directions flat at tree-level, One-loop corrections in general lift the flat directions, but naturally give small negative squared masses similar to -g(2)H(2)/(4 pi)(2) for, all flat directions that do not involve the stop. No-scale supergravity of the SU(N, 1) type and the untwisted sectors from orbifold compactifications are special cases of this general set of models. We point out the importance of the preservation of flat directions for baryogenesis. C1 UNIV CALIF BERKELEY,LAWRENCE BERKELEY LAB,THEORET PHYS GRP,BERKELEY,CA 94720.

Some of them are believed to break supersymmetry dynamically. We propose a simple technique to analyze these models. Introducing a vector-like field into the model, one finds flat directions where one can study the dynamics, We unambiguously show that the supersymmetry is broken when the mass of the vector-like field is small but finite, and hence the Witten index vanishes, If we increase the mass of the vector-like field, it eventually decouples from the dynamics and the models reduce to the original non-calculable models. Assuming continuity of the Witten index in the parameter space, one can establish dynamical supersymmetry breaking in the non-calculable models.

ANNIHILATION; COLLISIONS; PHYSICS; Z(0) AB Measurements are presented of short range three-particle correlations in e(+)e(-) annihilations at LEP using data collected by the DELPHI detector. At small values of the four-momentum difference, strong three-particle correlations are observed for like-sign (+++ and ---) and for unlike-sign (++- and +--) pion combinations which are not a consequence of two-particle correlations. A possible explanation of the observed effects in like-sign combinations is the existence of higher order Bose-Einstein interference, which significantly changes the particle distributions in jets.

The analysis presented here couples the final states pi(0) pi(0) pi(0), pi(0) pi(0) eta and pi(0) eta eta of ($) over bar pp annihilation at rest. It is based on a 3 x 3 K-matrix. We find masses and widths of M = (1390 +/- 30) MeV, Gamma = (380 +/- 80) MeV; and M = (1500 +/- 10) MeV, Gamma = (154 +/- 30) MeV, respectively. The product branching ratios for the production and decay into pi(0) pi(0) and eta eta of the f(0)(1500) are (1.27 +/- 0.33) . 10(-3) and (0.60 +/- 0.17) . 10(-3), respectively.

Sequence analysis showed that this Alu element is flanked by perfect direct repeats and a 3' oligo(dA)-rich tail, The Alu element, designated A25, is deleted by 34 nucleotides at the 5' end and has a single CpG mutation compared to the human-specific consensus sequence. Using a PCR-based assay, we demonstrated that the A25 Alu repeat is localized to human chromosome 8 and is polymorphic in humans.

Planar laser-induced fluorescence imaging of the evolving layer, produced by a perturbed SF6 planar jet in air, shows an apparent flow bifurcation that is observed as mushroom-shaped or sinuous-shaped interfacial patterns. Analysis of this nonlinear instability growth, accomplished by modelling the flow field as a row of line vortices, predicts that the layer thickness grows logarithmically at later times and compares well with our measurements. Because the row of vortices is unstable, the model also provides an explanation for the appearance of the three observed interfacial patterns. C1 LOS ALAMOS NATL LAB,LOS ALAMOS,NM 87545.

Since no assumptions are made on the length scales, the equations can be applied to a fluid of arbitrary depth and to disturbances with arbitrary wavelength. For one-dimensional gravity waves, these evolution equations are reduced to those derived by Matsuno (1992). Most of the known equations for surface waves are recovered from the new set of equations as special cases. It is shown that one set of equations has a Hamiltonian formulation and conserves mass, momentum and energy. The analysis for irrotational flow is extended to two-dimensional uniform shear flow.

On insulators, the major contribution to the surface polarizability at low frequencies is from surface ions. The mobility of these ions depends strongly on the humidity. Using polarization forces we have been able to image liquid films, droplets, and other weakly adsorbed material. (C) 1995 American Institute of Physics.

Furthermore, new global detectors have been added to gain insight into the reaction dynamics and enable studies of flow effects. The report presents preliminary rapidity distributions for protons and produced mesons in central collisions. The shape of m(t)-spectra of pions is discussed. Examples of the measurements which can be done with a new multiplicity array are presented. C1 UNIV CALIF BERKELEY,SPACE SCI LAB,BERKELEY,CA 94720. COLUMBIA UNIV,NEW YORK,NY 10027.

The production of single photons in 200 A GeV S+Au reactions has been investigated using the 3800 element Pbglass calorimeter of CERN experiment WA80. Neutral pi(0) and eta cross sections have been measured via their two-photon decay branch yields. In a first analysis of the WA80 results, a slight excess photon yield above that which may be accounted for by hadronic decays was observed for central collisions. A report on the status of the reanalysis of this data is presented. RP ALBRECHT, R (reprint author), OAK RIDGE NATL LAB,OAK RIDGE,TN 37831, USA.

The S+Pb data was taken with two different experimental configurations, and the results agree well with each other. The effects of a new Monte Carlo simulation of the NA36 TPC on the efficiency calculations are discussed. The Lambda rapidity and multiplicity distributions are then compared to three theoretical models of heavy ion interactions, and to the NA35 results. There is still a significant disagreement between the two experiments. The comparison to the models indicates that reinteractions of secondaries are important in explaining the observed Lambda yields. Finally, the yields of doubly strange baryons in S+Pb interactions have been recalculated using the new efficiencies. The ratios of double to singly strange baryons are unchanged from the previously published results. C1 UNIV STRASBOURG 1,CTR RECH NUCL,CNRS,IN2P3,F-67037 STRASBOURG,FRANCE.

We find that domains of disoriented chiral condensate with 4-5 fm in size can form through a quench while an annealing leads to domains of smaller sizes. We also demonstrate that quenching cannot be achieved by relaxing a chirally symmetric system through expansion. Furthermore, we point out that the order of the phase transition has little significance for the domain formation. C1 UNIV CALIF BERKELEY,LAWRENCE BERKELEY LAB,THEORET PHYS GRP,BERKELEY,CA 94720.

Imposing boost invariant initial conditions at an initial proper time tau(0) and starting from an approximate equilibrium configuration, we investigate the possibility of formation of disoriented chiral condensate during the expansion. In order to create large domains of disoriented chiral condensates low-momentum instabilities have to last for long enough periods of time. Our simulations show no instabilities for an initial thermal configuration. For some of the out-of-equilibrium initial states studied, the fluctuation in the number of particles with low transverse momenta become large at late proper times.

I emphasize that while the predictions are strongly model dependent, nevertheless substantial shifts in the thermal rho mass are expected to occur at the point of phase transition. As long as the thermal rho peak does not become too broad, this should provide a striking signature of the existence of a phase transition.

After the system has cooled and expanded, nucleons in close proximity and moving with small relative momenta coalesce to form nuclei. Light nuclei production enables the study of several topics, including the mechanism of composite particle production, freeze-out temperature, size of the interaction region, and entropy of the system. NA44 is the only relativistic heavy-ion experiment to have both deuteron and anti-deuteron results in both pA and AA collisions and the first CERN experiment to study the physics topics addressed by d and (d) over bar production.

A Fourier decomposition of the azimuthal transverse energy distributions in different regions of pseudorapidity is performed as a function of the centrality in order to describe the event shape. The extracted coefficients are compared to model predictions. Using the E877 forward spectrometer, triple differential cross section for protons and pi(+) are measured with respect to the reaction plane determined by calorimeters. The variation of slope parameters at different orientations to the reaction plane is obtained by fitting to thermal Boltxmann distributions. C1 WAYNE STATE UNIV,DETROIT,MI 48202.

Based on Fermi's golden rule, we allow spontaneous transitions to occur between the wave packets which are not energy eigenstates. The ensuing diffusive evolution in the space of the wave packet parameters exhibits appealing physical properties, including relaxation towards quantum statistical equilibrium.

In principle, the largest barrier to a clean interpretation of the experimental results is contamination by foreground sources. We address this issue by projecting out likely sources of foreground contamination from seven separate small-angle and medium-angle experiments. All of the experiments are consistent so far with the simplest inflationary models; for n = 1 the experiments' combined best-fit quadrupole amplitude is Q(rms-ps) = 18(-1)(+3) mu K, in excellent agreement with the Cosmic Background Explorer two-year data.

COLLIDER SO PHYSICAL REVIEW LETTERS LA English DT Article ID COLLISIONS; TEV AB The properties of two-, three-, four-, five-, and six-jet events with multijet masses >600 GeV/c(2) are compared with QCD predictions. The shapes of the multijet-mass and leading-jet-angular distributions are approximately independent of jet multiplicity and are well described by the NJETS matrix element calculation and the HERWIG parton shower Monte Carlo predictions. The observed jet transverse momentum distributions for three- and four-jet events discriminate between the matrix element and parton shower predictions, the data favoring the matrix element calculation.

PROTON-ANTIPROTON COLLISIONS AT ROOT-S=1.8 TEV SO PHYSICAL REVIEW LETTERS LA English DT Article ID FERMILAB TEVATRON; COLLIDER; MODEL; PARTICLES; DETECTOR; HIGGSINO; MASS; LEP AB We have sought evidence for radiative decays of neutralinos produced in proton-antiproton collisions at root s = 1.8 TeV. Events containing two photons plus large missing transverse energy were investigated. The observed event rate and the missing transverse energy distribution of the two-photon events are consistent with QCD predictions. Inferred limits on squark and gluino masses depend on the supersymmetry model parameters. The particular choices mu = -40 GeV/c(2) and tan beta = 1.5 lead to 90%-confidence-level asymptotic lower limits of 110 GeV/c(2) and 140 GeV/c(2) for squarks and gluinos, respectively.

SUPERSYMMETRIC PARTICLES; CASCADE DECAYS; MASS BOUNDS; COLLIDER; PHYSICS AB We present a search for events consistent with the production and decay of the squarks and gluinos of the minimal supersymmetric standard model (MSSM) in the D0 detector at the Fermilab Tevatron
collider. We examined data for events containing large missing transverse energy and three or more jets. We observed no excess of events above the expected yield from standard model processes. For a choice of MSSM parameter values, we set a lower limit at the 95% confidence level on the mass of the gluino of 144 GeV/c(2) for all squark masses and a lower limit of 212 GeV/c(2) for equal squark and gluino masses.

ID IONIZATION; STATES
AB Photoelectron energy spectra resulting from two-photon ionization of calcium atoms by 180 fs pulses have been studied as a function of wavelength (380-405 nm) and intensity (9-900 GW/cm(2)). When the wavelength is tuned near the 4s --> 4p or 4s --> 5s ionic core transition, the photoelectron peaks display a characteristic splitting proportional to the field strength and assignable to a two-electron continuum-continuum Autler-Townes effect. Spectra obtained by an essential-state model involving three coupled continua are compared to the experiment.

AB Fusion-produced alpha particles with energy less than or equal to 0.7 MeV have been spectroscopically observed in the core of a deuterium-tritium plasma in the TFTR tokamak at alpha densities of 3 x 10(16) m(-3). During a sawtooth-free discharge, the measured energy spectra at r/a = 0.3 are in good agreement with those predicted on the basis of collisional transport. Time-resolved measurements during the alpha thermalization after alpha source turn-off show decay of the distribution function to lower energies consistent with the classical slowing-down time of 0.5 s.

AB Recent experiments on Bi2Sr2CaCu2O8-y superconductors at zero magnetic field have been performed with a transformer configuration of contacts. We interpret the experimental data on the basis of large-scale Langevin dynamical simulations of a three dimensional (3D) Josephson lattice with a current bias through a single plane. We show that the experimentally observed effects can be attributed to linking thermal vortex loop excitations that cause voltages in neighboring superconducting planes to lock in a narrow temperature range near the 3D phase transition.

AB We have determined the magnetic response S(omega) of UCu5-xPdx (x = 1, 1.5) for temperatures T ranging from 12 to 300 K and energy transfers omega from 0.5 to 200 meV. S(omega) is virtually identical in the two compounds, displaying localized moment dynamics for omega greater than or similar to 25 meV. For omega < 25 meV, temperature provides the only energy scale for the magnetic excitations with the dynamical susceptibility described by a universal scaling function chi''(omega,T) similar to omega-(1/3)Z(omega/T). We argue that S(omega) represents critical scattering associated with a T=0 phase transition, whose origin lies with the magnetic screening of individual uranium ions.

AB A set of coupled equations of motion for the evaluation of spin dynamics in magnets is introduced. This adiabatic approach considers the orientation of the local magnetic moments to be slowly varying relative to their magnitudes. The method is implemented within the local density approximation and applied to gamma-Fe, a frustrated system where we obtain new low energy magnetic configurations.

ID LA2-XSRXCUO4; SUPERCONDUCTIVITY; CLUSTER; NMR; NQR
AB I report the results of ab initio quantum chemistry calculations addressing the nuclear quadrupole resonance (NQR) spectra of hole-doped La2CuO4. The experimental spectra point to two Cu environments, with a main peak, corresponding to a predominantly d(9) Cu site, and a satellite at similar to 3 MHz higher frequency. The cluster calculations exhibit broken-symmetry solutions in which an additional hole localizes on a single CuO6 unit, and predict a satellite in the NQR spectrum 2.7 MHz above the main peak. The satellite corresponds to Cu sites neighboring a localized hole. I conclude that some (similar to 25%) of the holes doped in to La2-xSrxCuO4 are localized on the NQR time scale of similar to 1 mu sec.

AB We use dispersed fluorescence (DF) and stimulated emission pumping (SEP) spectroscopies on the B ($) over tilde (2)A'-X ($) over tilde (2)A' system of jet-cooled HCO to measure the vibrational energies, resonance widths, and relative fluorescence intensities of 73 bound and resonance states supported by the ground-state potential energy surface. The SEP experiments use both two-color resonant four-wave mixing (RFWM-SEP) and the more conventional technique in which SEP signals are obtained from fluorescence depletion (ED-SEP). Where applicable, RFWM-SEP provides superior spectra to those obtained with ED-SEP which is susceptible to saturation broadening that can prevent accurate determinations of resonance widths. The observed bound and resonance states span an energy range of 2000-21 000 cm(-1) and comprise a wide range of vibrational excitation among the three vibrational modes, including states with 1-12 quanta of excitation in the C-O stretch, 0-5 quanta of bending excitation, and 0-1 quanta of excitation in the C-H stretch. The widths are markedly mode-specific and often display striking, nonmonotonic variations with increasing C-O stretch excitation. We compare our results to those of previous DF and SEP studies and to recent dynamical calculations of resonance energies and widths that use realistic potential surfaces derived from ab initio calculations. The resonance widths are particularly sensitive gauges of the unimolecular dissociation dynamics and provide stringent tests of theoretical potential surfaces. (C) 1995 American Institute of Physics.

AB A modified self-consistent-held (SCF) theory is introduced and applied to hard-site Gaussian chains at meltlike density in contact with a hard wall. The traditional Edwards, quantum theoretical approach to inhomogeneous polymeric systems is used, but the solvent induced potential is calculated by density functional (DF) methods where the polymer reference interaction site model (PRISM) theory is used to calculate the ''input'' for the potential calculation. Specific calculations were performed with DF theory, Helfand-Tagami SCF theory, and modified-SCF theory. It is seen that the modified-SCF theory is capable of capturing the major structural features predicted by DF theory, and it promises to be a useful bridge between the SCF and DF theories.

AB The He-I, -II photoelectron (PE) spectra of the carbonyl dihalides, COF2, COCl2 and COBr2, and the He I spectra of the mixed carbonyl halides COCIF, COBrF and COBrCl have been recorded. The assignments of the photoelectron peaks are discussed with reference to ab initio electronic structure calculations in the Hartree-Fock. configuration interaction (CI) and Green's function (OVGF and 2ph-TDA) formalisms and the preferred assignments tabulated. Koopmans' theorem results in a systematic overestimate of the ionisation energies whereas the two Green's function methods give ionisation energies in very good agreement with the spectra, with errors of as little as 0.3 eV for the outer valence orbitals. A long standing problem with the assignments of the photoelectron spectra of COCl2 was resolved by the use of multi-reference CI calculations on the low-lying states-of the ion. The trends. in the halogen-dependent ionisation energies are discussed in terms of the halide inductive effects and the energies of the halogen lone-pair orbitals relative to the pi-bonding orbital of CO.

AB We report the first experimental demonstration of cavity-induced resonances that occur without total internal reflection. We obtained these resonances by observing the fluorescence spectrum from the molecules enclosed within a small, lossy capillary of the type used for capillary zone electrophoresis. Even with weak reflections from the capillary inner walls, enough feedback exists to superimpose resonances on the otherwise smooth fluorescence spectrum. These resonances, commonly called morphology-dependent resonances or whispering-gallery modes, have typically been observed only in cavities in which total internal reflection is present.

AB The formalism by Press and Schechter (PS) is often used to infer number densities of virialized objects of mass M (e.g., quasars, galaxies, clusters of galaxies, etc.) from a count of initially overdense regions in a Gaussian density perturbation field. We reanalyze the PS formalism by explicitly counting underdense regions which are embedded within overdense regions, so-called cloud-in-clouds. In contrast to the original PS formalism, our revised analysis automatically accounts for all the cosmic material. We find that mass distribution functions for virialized objects are altered by the solution of the cloud-in-cloud problem. These altered distribution functions agree much better with distribution functions inferred from N-body simulations than the original PS distribution functions.

AB We present an analysis of multifrequency measurements of atmospheric emission in the Rayleigh-jeans portion of the cosmic microwave background spectrum (1-90 GHz) taken since 1986 from White Mountain, CA, and from the South Pole. Correlations of simultaneous data at 10 and 90 GHz and accurate low-frequency measurements show good agreement with model predictions for both sites. Our data from the South Pole 1989 campaign combined with real-time measurements of the local atmospheric profiles provide accurate verification of the expected independent contributions of H2O and O-2 emission. We show that variations on the order of 10% of the oxygen emission (both resonant and nonresonant components) are present on timescales of hours to days, mainly due to the evolution of the atmospheric pressure profile. Oxygen emission fluctuations appear larger than previously expected and may have significant consequences for ground-based cosmic microwave background experiments.

AB Supernova-driven outflows produced by intense bursts of star formation can drastically affect the structure and subsequent evolution of dwarf galaxies. Extensive mass loss from such systems may also provide an important source of chemical enrichment for the intergalactic medium. Despite the potential importance of these outflows, there is a very limited amount of direct observational evidence for their existence. One of the clearest signatures of a starburst-driven outflow is the X-ray emission from the hot gas that drives the outflow. We have therefore undertaken an X-ray imaging and optical spectroscopic investigation of the nearest and best-studied starbursting dwarf galaxy NGC 1569 using the HRI on ROSAT and the Ritchey-Chretien spectrograph on the KPNO 4 m telescope, respectively. We find that at least half the keV X-ray emission of NGC 1569 is associated with a diffuse halo that is some 3.'8 x 2.'2 similar to 2.4 x 1.5 kpc in size. Kiloparsec-scale ''spurs'' of diffuse X-ray emission extend outward along or near the optical minor axis of the galaxy. These diffuse X-ray spurs are morphologically associated with the well-known system of H alpha filaments. Previous kinematic studies have suggested that the H alpha filament system is a bipolar outflow. Our new optical spectroscopic data show that the H alpha emission comprises two kinematically distinct components: a quiescent system about 1 kpc in size responsible for about 75% of the H alpha emission and a fainter and more complex system over 2 kpc in size with radial velocities of as much as +/-200 km s(-1) relative to v(sys). The latter appears to define expanding hollow structures consisting of several kiloparsec-scale ''superbubbles.'' The dynamical age of the high-velocity system (similar to 10(7) yr) is similar to various estimates of the age of the starburst. We also see very broad wings (full width at zero intensity of 1400-2300 km s(-1)) on the H alpha emission-line profile at the location of super starcluster A, suggestive of recent supernova activity there.
We argue that the starburst in NGC 1569 is driving an outflow of the interstellar medium on a global scale. Our simple models suggest that the X-ray emission is too bright to come primarily from the hot tenuous supernova-heated gas in the interior of a superbubble, unless this gas is evaporating or ablating cool dense material. This latter material may be the outer shell of the superbubble or interstellar clouds that have been engulfed by the superbubble. The high-velocity H alpha filaments probably correspond to the shocked and accelerated ambient material in the superbubble's outer walls, while the low-velocity material may be massive photoionized clouds in the starbursting galactic disk. The observed expansion speeds probably exceed the galactic escape velocity. It seems likely that the expanding material will ultimately ''blow out'' of the interstellar medium, and in so doing may allow most of the metals created by the starburst to escape from the galaxy. It is less clear whether the outflow will lead to the ejection of most or ah of this galaxy's interstellar medium, though it appears at least energetically feasible. We briefly discuss the significance of these results for ideas about the evolution of dwarf galaxies.

AB Differential rotation between the neutron star crust and a more rapidly rotating interior superfluid leads to frictional heating that effects the star's long-term thermal evolution and resulting surface emission. The frictional heating rate is determined by the mobility of the vortex lines that thread the rotating superfluid and pin to the inner crust lattice. If vortex pinning is relatively strong, a large velocity difference develops between the inner crust superfluid and the crust, leading to a high rate of heat generation by friction. Here we present the results of thermal evolution simulations based on two models of the vortex pinning forces that bracket a range of plausible pinning strengths. We include the effects of superfluidity, magnetic fields, and temperature gradients. As representative standard and accelerated neutrino emission processes taking place in the core, we consider the modified Urea process in normal baryonic matter, and the much faster quark Urea process. Comparison of our results with neutron star surface temperature data, including the recent temperature measurement of the Geminga pulsar, shows that stars with soft equations of state and modest frictional heating are in closest agreement with the data; stars with stronger frictional heating have temperatures inconsistent with the upper limit of PSR 1929+10. Stiffer stars undergoing standard cooling generally have temperatures lying above the Vela detection, a situation worsened by the inclusion of frictional heating. Stars undergoing accelerated cooling without frictional heating have temperatures that fall far below most temperature measurements; the Vela and Geminga detections being the most compelling examples. Only in stiff stars, which have thick crusts, can the inclusion of strong frictional heating raise the temperature at late stages in the evolution to a level consistent with the data. However, such a large amount of heating leads to a temperature at similar to 1000 yr in excess of the Crab upper limit. Suppression of accelerated neutrino emission processes, perhaps by superfluid pairing in the core, may yield acceptable cooling models.

AB The evolution of helium stars with initial masses in the range 4-20 M. is followed through all stages of hydrostatic nuclear burning. We identify these objects as Wolf-Rayet stars that have lost their hydrogen envelopes, either before or early in their helium-burning phase, probably because they were in a mass-exchanging binary system or, for the more massive stars, because they were subject to a strong stellar wind. Stripped of their envelopes, these stars are subject to efficient (mass-dependent) mass loss. As a result, the final masses converge to a narrow range of small values: 2.26-3.55 M. for all stars considered. We identify these as progenitors of Type Ib and, perhaps, Type Ic supernovae and investigate the dependence of the presupernova structure on the initial mass of the helium star. For two models, the extra mass loss that could occur in a close binary, the product of common envelope evolution, is also considered. Five of our presupernova models are then exploded, using pistons, and their nucleosynthesis and bolometric light curves calculated. Peak luminosities are in the range (1.5-4) x 10(42) ergs s(-1). The (unmodified) mass of Ni-56 for 10 explosions (variable parameterizations of explosion in the five stars) lies in a narrow range, 0.07-0.15 M. Other abundances. from carbon through nickel are coproduced in approximately solar proportions along with interesting amounts of the long-lived radioactivities, Al-26 and Fe-60. The light curves agree reasonably well with observations of Type Ib and Ic supernovae, including Type Ib SN 1983N and the recent Type Ic SN 1994I. A Ni-56 mass of 0.05(-0.01)(+0.02) M. is derived for the latter (for a distance of 7 Mpc), and speculations are presented regarding SN 1998bg. Ultimately, spectroscopic diagnostics of these models should aid in testing them.

AB The majority of the cosmic rays in our Galaxy with energies in the range of similar to 10(l0)-10(14) eV are thought to be accelerated in supernova remnants (SNRs). Measurements of SNR gamma-ray spectra in this energy region could support or contradict this concept. The Energetic Gamma-Ray Experiment Telescope (EGRET) collaboration has reported six sources of gamma rays above 10(8) eV whose coordinates are coincident with SNRs. Five of these sources are within the field of view of the CYGNUS extensive air shower detector. A search of the CYGNUS data set reveals no evidence of gamma-ray emission at energies similar to 10(14) eV for these five SNRs. The flux upper limits from the CYGNUS data are compared to the lower energy fluxes measured with the EGRET detector using Drury, Aharonian, and Volk's recent model of gamma-ray production in the shocks of SNRs. The results suggest one or more of the following: (1) the gamma-ray spectra for these five SNRs soften by about 10(14) eV, (2) the integral gamma-ray spectra of the SNRs are steeper than about E(-13), Or (3) most of the gamma rays detected with the EGRET instrument for each SNR are not produced in the SNR's shock but are produced at some other site (such as a pulsar).

AB The use of AFM for in-line monitoring of an interlevel dielectric via plasma etching step is reported. By comparing etch depths, to via types contacting bath Au- and W-based metals, the AFM can non-destructively determine whether micrometre-sized vias have been cleared. Owing to the etch selectivity of the SF6/O-2 plasma, the Au-based ohmic metal acts as an etch stop whereas the W-based refractory gate contact continues to etch.

AB Microcell hybrids containing various regions of human chromosome 8 were formed by microcell-mediated transfer of neo-tagged chromosome 8 into the cells derived from severe combined immunodeficiency (SCID) mouse. Thus, 110 cosmid markers were isolated from SV40-transformed SCID fibroblast cell line (SCVA) containing a p12-q11.1 region of human chromosome 8 and were assigned to eight regions in 8p12-q11.1, using a microcell-hybrid panel. For positional cloning of a human gene that restores the DNA-repair defect in a mouse with SCID on 8p11.1-q11.1 (SCID region), we constructed a yeast artificial chromosome (YAC) contig of about 4.5 Mb. Overlapping YACs were further aligned by restriction mapping, using rare-cutting restriction endonucleases. The cosmids and YAC contig should facilitate isolation of the SCID gene and other genes, such as the Werner syndrome-responsible gene in or near this region. (C) 1995 Academic Press, Inc.

AB Atmosphere-surface exchange fluxes can vary significantly over a large grid cell of atmospheric models and need to be estimated with subgrid-scale variations included. The present study aims at developing a method for parameterization of subgrid-scale (PASS) surface fluxes in atmospheric models, with emphasis on a scheme to distribute the mean atmospheric forcing from the model grid (MG) to subgrid (SG) cells and on using spectral vegetation indices derived from satellite remote sensing to estimate surface parameters at SG scales. The mean atmospheric forcing, including wind speed, temperature, and humidity, is distributed to SG cells according to spatial differences in these parameters at the surface and the strength of vertical turbulence mixing in the atmospheric boundary layer. Simulation with this scheme allows a feedback of changed SG atmospheric conditions caused by surface heterogeneity to influence the SG surface exchange. The SG surface exchange is parameterized with a suite of simplified relationships developed to infer surface conductance, aerodynamic resistance, surface albedo, and soil heat flux ratio on the basis of spectral vegetation indices available from satellite remote sensing, while empirical coefficients used in the relationships are derived for selected surface types from available field experiments. The computation of the surface flux and energy budget for a large number of SG cells is made feasible by using a rapid scheme based on an analytical solution to the surface energy budget equations. The PASS model was tested in a single-cell mode with field measurements and evaluated in a multicell mode with limited data and a sensitivity study.

These results are based on atomic absorption measurements of Pb(g) number densities and laser-induced fluorescence measurements of relative PbBr(g) number densities in equilibrium with PbBr2(g) at temperatures between 700 and 850 degrees C. The laser-induced fluorescence excitation spectrum of PbBr(A-X), excited between 467 and 485 nm and observed between 516 and 536 Mm, is reported. Lifetime measurements of PbBr(A) at various PbBr2 number densities yielded a collision-free lifetime of similar to 200 ns and a PbBr2 collisional quenching constant of 1.42 x 10(-9) cm(3) molecule(-1) s(-1).

AB High resolution XPS, HREELS, and TPD data indicate two distinct binding modes for methyl thiolate with clearly distinct reactivites on the Ni(111) surface. At low temperatures methyl thiolate is adsorbed primarily at low coordination, probably bridging, sites with the C-S bond tilted toward the surface and undergoes hydrogenolysis near 275 K. Between 150 and 250 K, a fraction of the bridge bonded thiolates are converted to thiolates in hollow sites with their C-S bonds oriented nearly perpendicular to the surface. The C-S bond in the hollow bonded thiolate is more stable and does not undergo hydrogenolysis until around 300 K. Overall, about 80% of the chemisorbed thiolates undergo hydrogenolysis (an overall disproportionation reaction) to form methane in the 250-350 K temperature range. The remaining 20% of the thiolates are completely dehydrogenated to form adsorbed atomic carbon and sulfur. Coadsorbed hydrogen favors formation of the thiolate in the bridge site. In the presence of coadsorbed deuterium, a substantial fraction of the methane formed is multiply deuterated (-d(2) and higher); however, no kinetic isotope effect is observed for the methane formation reaction. These results suggest C-S bond breaking as the rate determining step for methane formation.

AB The sensitivity of W and Z production at RHIC to the possible (u) over bar/(d) over bar asymmetry in the proton is studied. The ratios of the W+ over W- production cross sections in p + p collision, as well as the ratios of the W+ and Z production cross sections for p + p over p + d collisions, are shown to be sensitive to this asymmetry. Predictions of various theoretical models for these ratios are presented.

AB Solid-liquid interfaces represent systems of great and diverse technological importance. Nevertheless, molecular scale surface science studies have so far been carried out primarily at solid-gas and solid-vacuum interfaces. In recent years, several optical and scanning probe techniques have become available that permitted molecular scale studies of solid-liquid interfaces. This paper reviews results from solid-gas interface studies as viewed from the perspective of relevance to solid-liquid interfaces, and correlates data obtained at the two interfaces wherever it is possible.

AB The details of the underpotential deposition (UPD) of Cu on Pt(111) in the presence of Cl- were re-examined using a combination of familiar ex-situ techniques (AES/LEED) and new in-situ techniques, anomalous surface X-ray scattering (SXS) and Cu2+ flux measurements using a rotating ring disk configuration with the Pt(111) single crystal as the disk electrode. In combination these techniques show definitively that Cu UPD occurs in a two step process, the first being the formation of a Cu-Cl adlattice having a bi-layer structure similar to the (111) plane of CuCl, the second being the formation of a pseudomorphic Cu monolayer covered with a Cl adlayer. The latter appears to have a structure similar to the structure of Cl adsorbed on Cu(111) to saturation in UHV.

AB The electrodeposition of Tl on Au(100) has been investigated using surface X-ray scattering. At potentials prior to Tl bulk deposition, Tl adatoms form a c(p X 2) close-packed monolayer on the unreconstructed Au(100) surface in both acid and alkaline solutions. The Tl monolayer uniaxially compresses over a 0.25 V wide potential range and the nearest-neighbor-separation of Tl attains a minimum value of 3.34 Angstrom. This is close to the value obtained on Au(111) prior to bulk Tl deposition. From the specular X-ray reflectivity, a 2.55 Angstrom Au-Tl layer spacing is obtained for the c(p X 2) monolayer. Bulk deposition of Tl at potentials negative of the reversible Nernst potential results in the formation of imperfectly-aligned hexagonal-close-packed crystallites on top of the c(p X 2) monolayer. At potentials positive to the stripping of the c(p X 2) monolayer, a (2 X 2) diffraction pattern is observed in perchloric and sulfuric acid solutions but not in alkaline solutions. Real space models are proposed.

AB Classical molecular dynamics is used to model the structure and dynamics of electric double layers that form when a metal electrode is in contact with an aqueous electrolyte solution containing simple ions and neutral organics. First attention is focused on the distribution of ions and neutrals next to an uncharged electrode. The electric field and potential across the system are calculated. The iodide ion adsorbs from neutral solution and causes a negative shift in the potential of zero charge (PZC) relative to fluoride. Adsorbed benzene causes a small positive shift of the PZC. Benzene desorbs when the metal electrode is charged and the surface electric field causes a layer of localized and oriented water to form next to the electrode. Non contact adsorbed hydrated sodium ions are more effective than contact adsorbed chloride in desorbing benzene.

SO JOURNAL OF THE AMERICAN CHEMICAL SOCIETY
LA English
DT Article
ID NUCLEAR MAGNETIC-RESONANCE; SPIN RELAXATION; GAS; TEMPERATURE; EXCHANGE;

AB A new technique for monitoring the formation of xenon clathrate hydrates is presented. Under controlled-temperature conditions, clathrate formation is studied with optically enhanced Xe-129 NMR spectroscopy, which allows the observation of the xenon occupation of both small and large clathrate cages. The experiments were performed in a temperature range of 170 to 258 K. Only in the range of 195 to 233 K did clathrate formation occur, with applied pressures of typically 0.3 MPa. The NMR data are analyzed with a simple kinetic model, which provides a rate coefficient for clathrate formation and a time constant which describes the decay of the NMR signal intensity. The analysis of the rate coefficients and occupancy ratios of the large to the small cages under the different experimental conditions enabled us to obtain some novel information on the hydrate phase formed on ice surfaces. The results suggest that the surface phase formed initially has many more occupied small cages than the bulk phase at equilibrium and that the composition evolves toward that of the bulk phase in a few minutes. At higher temperatures (258 K) the surface phase seems to be less stable than the bulk phase.

AB Complexity originates from the tendency of large dynamical systems to organize themselves into a critical state, with avalanches or ''punctuations'' of all sizes. In the critical state, events which would otherwise be uncoupled become correlated. The apparent, historical contingency in many sciences, including geology, biology, and economies, finds a natural interpretation as a self-organized critical phenomenon. These ideas are discussed in the context of simple mathematical models of sandpiles and biological evolution. Insights are gained not only from numerical simulations but also from rigorous mathematical analysis.

AB We present a controlled image smoothing and enhancement method based on a curvature flow interpretation of the geometric heat equation. Compared to existing techniques, the model has several distinct advantages. (i) It contains just one enhancement parameter. (ii) The scheme naturally inherits a stopping criterion from the image; continued application of the scheme produces no further change. (iii) The method is one of the fastest possible schemes based on a curvature-controlled approach.

AB A modified epitaxial design leads to straightforward implementation of short (1 lambda) optical cavities and the use of C as the sole p-type dopant in AlGaInP/AlGaAs red vertical-cavity surface-emitting lasers (VCSELs). Red VCSELs fabricated into simple etched air posts operate continuous wave at room temperature at wavelengths between 674 and 690 nm, with a peak output power as high as 2.4 mW at 690 nm, threshold voltage of 2.2 V, and peak wallplug efficiency of 9%. These values are all significant improvements over previous results achieved in the same geometry with an extended optical cavity epitaxial design. The improved performance is due primarily to reduced optical losses and improved current constriction and dopant stability. (C) 1995 American Institute of Physics.

AB Low-temperature, T<90 K, illumination transfers transparent, single crystals of AlSb doped with Se to a metastable state characterized by a high optical absorption approaching 200 cm(-1) The enhanced absorption spectrum extends from 0.1 to 1.5 eV and consists of a double band structure with peaks at 0.2 and 0.5 eV. It is induced by photons with a threshold energy of about 1 eV. It is persistent, i.e., it shows no measurable decay after switching off the excitation. The low absorption state is thermally recovered at 100 K. The persistent absorption is a manifestation of a DX-type bi-stability of the Se donor. The 0.2 and 0.5 bands are, respectively, due to the photoionization of electrons from the metastable hydrogenic donor level to X(1) and X(3) conduction band minima. A large binding energy of the Se donor is essential for the observation of persistent absorption and a lack of any free-electron related effects. (C) 1995 American Institute of Physics.

AB Double J/psi production on the order of 20-30 pb has been observed by the NA3 collaboration. These psi psi pairs, measured in pi(-N) interactions at 150 and 280 GeV/e and in pN interactions at 400 GeV/c, carry a large fraction of the projectile momentum, x(psi psi) greater than or equal to 0.6 for the 150 GeV/c beam and greater than or equal to 0.4 at 280 GeV/c. We examine several sources of psi psi pair production within QCD, including O(alpha(s)(4)) psi psi production, leading-twist b $$($) over bar b production and decay, and the materialization of heavy-quark Fock states in the projectile. We estimate the production cross section and the single and double J/psi momentum and mass distributions for each, comparing the results with the NA3 data, and predict psi psi production in pN interactions at 800 GeV/c, accessible to current fixed-target experiments. We also discuss the observable implications of open heavy meson pair production from the intrinsic heavy quark Fock states.

AB Supersymmetry breaking in the early Universe induces scalar soft potentials with curvature of the order of the Hubble constant. This has a dramatic effect on the coherent production of scalar fields along flat directions. For moduli fields, this breaking generically gives a concrete realization of the moduli problem by determining the field value at early times. However, it suggests a solution if the minimum of the induced potential coincides with the true minimum. For the Affleck-Dine mechanism, large squark and slepton expectation values generally do not result if the induced soft mass squared is positive, but they do occur if it is negative. An acceptable baryon asymmetry can be obtained without subsequent entropy releases and is related to the mass of the lightest neutrino.

AB A nonlinear truncation procedure for Fourier-Hermite expansion of Boltzmann-type plasma equations is presented which eliminates fine velocity scale, taking into account its effect on coarser scales. The truncated system is then transformed back to (x, v) space which results in a renormalized Boltzmann equation. The resulting equation may allow for coarser velocity space resolution in kinetic simulations while reducing to the original Boltzmann equation when fine velocity scales are resolved. To illustrate the procedure, renormalized equations are derived for one dimensional electrostatic plasmas in which collisions are modeled by the Lenard-Bernstein operator.

Subpicosecond laser pulses, focused to an intensity of 1 x 10(16) W/cm(2), create a fully ionized helium plasma. Measurement of the resulting emission spectrum allows a determination of the time-dependent electron velocity distribution. The initial distribution is found to be strongly non-Maxwellian and subsequent recombination kinetics proceed more slowly than predicted for a Maxwellian distribution of electrons.

AB We have performed direct Monte Carlo simulations of the reversible diffusion-limited process A + A <-> A to study the effect of fluctuations on a propagating interface between stable and unstable phases. The mean-field description of this process, Fisher's reaction-diffusion equation, admits stable nonlinear wave fronts. We find that this mean-field description breaks down in spatial dimensions 1 and 2, while it appears to be qualitatively and quantitatively accurate at and above 4 dimensions. In particular, the interface width grows similar to t(1/2) in 1D (exact) and similar to t(0.272+/-0.007) in 2D (numerical).

AB The magnetic domain structure of melt-spun giant magnetoresistant Au71.6Co28.4 samples in as-prepared and annealed states is determined by means of Lorentz microscopy using the JEOL-1000 atomic resolution microscope (ARM) in a modified diffraction mode. The interpretation of the domain structure is done by comparing magnetic contrasts observed in Fresnel mode with simulated contrasts using a geometrical algorithm based on the Lorentz equation. Cobalt precipitates 50 to 100 nm in diameter are found in a single domain state with a curling-like magnetization, that reduces their magnetic stray fields. Larger precipitates (approximate to 200 nm) are multidomain particles.

AB A small amount of water added to a supercritical fluid can greatly increase the solubility of polar species in nonpolar fluids. These modified supercritical solutions significantly expand the use of the fluids in separations and reactions. In order to successfully utilize these systems, information on the miscibility or solubility of water in the fluid is required. Often solubility data are not available for water in a supercritical fluid under a given set of temperature and pressure conditions, and a costly set of equipment must be assembled in order to make these measurements. A relatively fast and inexpensive technique to measure water solubilities using a simple long path length optical cell in an FT-IR spectrometer is described. This technique is also applicable to common and newly developed refrigerants where water solubilities are often unknown at temperatures much above ambient. In this paper, water solubility data in carbon dioxide and two types of refrigerants (chlorodifluoromethane, R22; 1,1,1,2-tetrafluoroethane, R134a) are presented for temperatures from approximately 40 to 110 degrees C and pressures from approximately 10 to 344.8 bar.

AB Spectral atomic emission intensity from laser-induced plasmas (LIPs) exhibits excellent correlation with atomic emission intensity in the inductively coupled plasma (ICP) for a wide variety of materials and laser powers. Laser ablation sampling with introduction into an ICP for chemical analysis has, among other factors, a strong nonlinear dependence on laser energy, spot size, and material composition. The LIP emission also has a similar nonlinear dependence and is shown to correspond with the ICP behavior. The correlation is demonstrated for several homogeneous metallic and oxide materials during laser ablation sampling over a range of power densities and incident laser beam spot sizes. The correlation is best for higher melting temperature materials and moderate laser power density. The LIP and ICP emission intensities both show similar dependence for mass ablation rate versus power density and laser beam spot size. A normalized ICP/area over LIP emission ratio shows that a functional relationship can be found for changes in ICP intensity with changes in laser power density. The correlation shows that the ICP intensity accurately reflects changes in the laser ablation process and that the LIP may possibly be used for internal monitoring during laser sampling with the ICP.

AB Tandem mass spectrometry is shown to improve the effective mass resolution in electrospray mass spectrometry. The technique involves selecting a population of ions within a narrow range of mass-to-charge values and allowing the ions to undergo proton transfer reactions. The shifts in mass-to-charge ratios associated with product ions formed by proton transfer allow for mass and charge assignment. The success of the technique relies on the relative enrichment of ions of a particular charge state that occurs in the mass-to-charge selection step. This approach can be used to extend the polymer mass range amenable to measurement, analyze mixtures that might otherwise be too complex for reliable mass measurements, and improve mass measurement precision when a mixture of cations is present within a given charge state. The technique is illustrated with a quadrupole ion trap using multiply-charged ions of cytochrome c, transfer ribonucleic acid from E. coli, strain W, and a synthetic deoxyribonucleic acid 30-mer.

AB The dissociation of cytochrome c ions (15+ charge state) generated by electrospray ionization has been studied by Fourier transform ion cyclotron resonance mass spectrometry (FTICR) using a sustained off-resonance irradiation/collision-iuduced dissociation (SORI-CID) technique. Over 95% of the fragment ions can be accurately assigned (to better than 10 ppm), yielding information on the primary sequences of the various proteins. Up to four stages of mass spectrometry (MS(4)) have been achieved without the need for quadrupole excitation/collisional cooling of the product ions. The subtle structural differences among the cytochrome c variants (from bovine, tuna, rabbit, and horse) are clearly reflected in their fragmentation patterns: replacing 3 out of 104 residues of the cytochrome c is shown to dramatically change the dissociation pattern. Of particular importance are a variety of results indicating that the dissociation of the cytochrome c's is influenced by higher-order structure and charge location, in addition to the primary structure (i.e., sequence). No fragmentation is observed in the region between residues 10-20 and little dissociation between residues 70-90. This is most likely due to the interactions of the heme group with the polypeptide chain, and such a heme ''footprinting'' pattern is analogous to the protein conformation in solution. These studies demonstrate that electrospray ionization-FTICR using SORI-CID can be a useful tool to probe not only the small differences in the primary sequences of proteins but also suggest the potential for probing their higher-order structures and yielding information not readily available from H/D exchange or circular dichoism studies.

AB The complete exon-intron organization of the human aggrecan gene has been defined, and the exon organization has been compared with the individual domains of the protein core. A yeast artificial chromosome containing the aggrecan gene was selected from the Centre d'Etude du Polymorphisme Humaine yeast artificial chromosome library, A cosmid sublibrary was created from this, and direct sequencing of individual cosmids was used to provide the exon-intron organization. The human aggrecan gene was found to be composed of 19 exons ranging in size from 77 to 4224 bp. Exon 1 is non-coding, whereas exons 2-19 code for a protein core of 2454 amino acids with a calculated mass of 254379 Da. Intron 1 of the gene is at least 13 kb. Overall, the sizes of the 18 introns range from 0.5 to greater than 13 kb. Each intron begins with a GT and ends with an AG, thus obeying the GT/AG rule of splice-junction sequences. The entire coding region is contained in 39.4 kb of the gene. The organization of exons is strongly related to the specific domains of the protein core. The A loop of G1 and the interglobular domain are encoded by exons 3 and 7 respectively. The B and B' loops of G1 are encoded by exons 4-6, and those of G2 are encoded by exons 8-10. These sets of exons, coding for the B and B' loops, are identical in size and organization. This is supported by the intron classes associated with these exons. Exon 11 codes for the 5' half of the keratan sulphate-rich region, and exon 12 codes for the 3' half of the keratan sulphate-rich region as well as the entire chondroitin sulphate-rich region. G3 is encoded by exons 13-18, including the alternatively spliced epidermal growth factor-like and complement regulatory protein-like domains. The correspondence between the exon organization and the protein domains argues strongly for modular assembly of the aggrecan gene.

ID RN-222
AB To study the importance of changes in atmospheric pressure on radon entry into houses, we have simultaneously measured the soil-gas entry into an experimental basement structure and the fluctuations in atmospheric pressure. Small amplitude (similar to 10 Pa), rapid (similar to 20 min) fluctuations in atmospheric pressure were an important driving force for soil-gas entry because 1) the characteristic time for the propagation of a pressure disturbance in the soil gas was similar to 2 min, and 2) the time-rate-of-change of these small fluctuations is often larger than that of the semi-diurnal oscillations. An analytical model has been derived for a structure with a subslab gravel layer based on a one-dimensional solution to the transient pressure diffusion equation. This model correctly predicts the temporal response of the measured soil-gas entry into the experimental structure , but underpredicts the amplitude.

AB We report optically-detected nuclear quadrupole resonance (ODNQR) of Eu3+ in LaF3. The anomalous nuclear quadrupole moments of Eu-151(3+) and Eu-153(3+) isotopes have been measured by detecting r.f.-induced quadrupole resonance which enhances the F-7(0)<->D-5(0) optical transition. Due to significant second-order hyperfine cancellation, the lowest quadrupole splitting in the ground state is only 6.95 MHz. In analysis of the ODNQR spectrum, an effective nuclear quadrupole Hamiltonian is diagonalized and the measured quadrupole splittings are used to determine the quadrupole interaction parameters for the ground state F-7(0). For Eu-151, P-151=2.67 and eta(151)=0.58, and for Eu-153, P-151=6.80 and eta(151)=0.49.

AB The electronic configurations of the actinide elements protide insights into the properties and chemistries of these elements and their compounds. It is the stability of these electronic structures which determines oxidation states and oxide stoichiometries, but these states are also important in less obvious aspects, such as the vaporization of oxides. Recent systematic evaluations of the vaporization/decomposition behavior of actinide oxides as a function of atomic number have provided important clues for understanding the underlying role of the actinide's f electrons in the vaporization of their oxides. The major factor in determining the primary mode of vaporization of the actinide oxides is the magnitude of the element's monoxide dissociation energy, which is linked to the promotion energy for the actinide's f electrons. This relationship provides both correlative and predictive methodologies for these actinide oxides. Some recent information on actinide oxide properties, the vaporization behavior of selected actinide oxides, and the systematic correlation of vaporization behavior with the electronic nature of the actinide are summarized here.

AB We report the results of inelastic neutron scattering (INS) studies of the J=0 to J=1 magnetic transitions in EuBa2Cu3O7. The low J values of these multiplets restrict our crystal field analysis to the second-order crystalline electric field (CEF) parameters obtained by fitting the splitting of the J=1 multiplet, and the spin-orbit coupling parameter, which is used to fit the energy of the J=0 to J=1 multiplet splitting. We compare our results with those derived from other INS studies on different rare earths, as well as with and derived from Mossbauer studies. The J=0 to J=1 splitting observed here is smaller than previously seen by optical spectroscopic studies on a variety of transparent, ionic compounds, necessitating the inclusion of a free-ion parameter in the fitting procedure. This work represents the first time that a complete excited multiplet has been seen for R in RBa(2)Cu(3)O(7). These results are particularly germane to crystal field analyses of the light rare earth ions in optically opaque materials, where assumptions about free-ion parameters are essential for a meaningful analysis.

AB The temperature dependencies of the lattice parameters in tetragonal HoPO4 and HoVO4 were measured using neutron powder diffraction techniques. Below about 100 K, the lattice parameter a of HoPO4 increases with decreasing temperature while c decreases. In HoVO4, the above behaviour is reversed, that is a decreases with decreasing temperature while c increases. Similar measurements on non-magnetic LuPO4 and LuVO4 do not show any anomaly. This observation indicates that the unusual temperature dependence of the lattice constants is magnetic in origin. The observed effect can be explained in terms of an Ho3+ quadrupole interaction with the crystalline lattice. In particular, the calculated electronically generated quadrupole moment of Ho3+ in HoPO4 and HoVO4 exhibits a temperature dependence similar to that observed for the lattice parameters.

AB Issues of self-consistency are reviewed for several unary equilibrium size distributions based on the capillarity approximation. Some apparent difficulties of interpretation are resolved. In terms of the kinetic approach to nucleation theory, the influence of self-consistency on the nucleation rate is shown to arise entirely from differences in the dimer evaporation rates for nearly all versions of classical theory. The nucleation rate behavior of the Kelvin model is explored. In this model, the Kelvin equation is used to prescribe all cluster evaporation rates. Nucleation rates predicted by the Kelvin model are quantitatively similar to those of the self-consistent classical (SCC) theory, but not to other simple versions of the classical theory. This behavior arises entirely from the relatively close coincidence of the SCC and Kelvin dimer evaporation rates. This means that, for the distribution-based versions of classical theory, the SCC model is the closest analogue of the Kelvin model. Because the Kelvin equation is fundamentally inadequate for very small clusters, the close relationship between the Kelvin and SCC formulations indicates that both are equally lacking in fundamental justification. The Kelvin model may, however, have some pragmatic utility, and a simple analytical rate expression is also derived for it to simplify the calculation of nucleation rates for this model.

AB Using the principle of detailed balance, we derive a new self-consistency requirement, termed the kinetic product rule, relating the evaporation coefficients and equilibrium cluster distribution for a binary system. We use this result to demonstrate and resolve an inconsistency for an idealized Kelvin model of nucleation in a simple binary mixture. We next examine several common forms for the equilibrium distribution of binary clusters based on the capillarity approximation and ideal vapor behavior. We point out fundamental deficiencies for each expression. We also show that each distribution yields evaporation coefficients that formally satisfy the new kinetic product rule but are physically unsatisfactory because they depend on the monomer vapor concentrations. We then propose a new form of the binary distribution function that is free of the deficiencies of the previous functions except for its reliance on the capillarity approximation. This new self-consistent classical (SCC) size distribution for binary clusters has the following properties: It satisfies the law of mass action; it reduces to an SCC unary distribution for clusters of a single component; and it produces physically acceptable evaporation rate coefficients that also satisfy the new kinetic product rule. Since it is possible to construct other examples of similarly well-behaved distributions, our result is not unique in this respect, but it does give reasonable predictions. As an illustrative example, we calculate binary nucleation rates and vapor activities for the ethanol-hexanol system at 260 K using the new SCC distribution and compare them to experimental results. The theoretical rates are uniformly higher than the experimental values over the entire vapor composition range. Although the predicted activities are lower, we find good agreement between the measured and theoretical slope of the critical vapor activity curve at a constant nucleation rate of 10(7) cm(-3) s(-2).

AB We numerically solve the complete set of coupled differential equations describing transient binary nucleation kinetics for vapor-to-liquid phase transitions. We investigate binary systems displaying both positive and negative deviations from ideality in the liquid phase and obtain numerical solutions over a wide range of relative rates of monomer impingement. We emphasize systems and conditions that either have been or can be investigated experimentally. In almost every case, we find behavior consistent with Stauffer's idea that the major particle flux passes through the saddle point with an orientation angle that depends on the rates of monomer impingement. When this is true, the exact numerical steady state nucleation rates are within 10%-20% of the predictions of Stauffer's analytical theory. The predictions of Reiss' saddle point theory also agree with the numerical results over a wide range of relative monomer impingement rates as long as the equilibrium vapor pressures of the two pure components are similar, but Stauffer's theory is more generally valid. For systems with strong positive deviations from ideality, we find that the saddle point approximation can occasionally fail for vapor compositions that put the system on the verge of partial liquid phase miscibility. When this situation occurs for comparable monomer impingement rates, we show that the saddle point approximation can be rescued by evaluating an appropriately modified nucleation rate expression. When the two impingement rates differ significantly, however, the major particle flux may bypass the saddle point and cross a low ridge on the free energy surface. Even in these rare cases, the analytical saddle point result underpredicts the numerical result by less than a factor of 10. Finally, we study the transition from binary to unary nucleation by progressively lowering the vapor concentration of one component. Both Reiss' and Stauffer's rate expressions fail under these conditions, but our modified rate prescription remains within 10%-20% of the exact numerical rate. (C) 1995 American Institute of Physics.

AB Molecular dynamics simulations of binary, athermal blends of chains consisting of 50 tangent sites were carried out over a range of compositions at liquidlike packing fractions. The sites interact with repulsive Lennard-Jones potentials and have effective hard sphere diameters of approximately 1.0 and 1.2 for the two site types. The intrachain and interchain correlation functions were found and, except for the single component systems, the interchain correlations were seen to de strongly dependent on system size. Trivial, long range correlations due to the finite system size can be approximated from simple physical arguments, and the coarse, interchain, radial distribution functions can be ''corrected'' for these effects. The resulting correlation functions are seen to behave at large separation as would be expected of interchain radial distribution functions in an infinite sized system, permitting meaningful comparisons with the predictions of liquid state theory.

AB Molecular dynamics simulations of a binary, athermal blend of chains consisting of 50 sites were carried out over a range of-compositions at an overall packing fraction of 0.465, The species in the blend interact with Lennard-Jones repulsive interactions chosen to give effective hard core diameters of 1.015 and 1.215 for the A and B sites, respectively. The intramolecular structure of the chains was seen to be weakly dependent on composition, with the mean-square end-to-end distance of the minority component at low volume fractions tending towards that of the host component. The three intermolecular radial distribution functions g(AA)(T), g(BB)(T), and g(AB)(r) were observed to increase with increasing concentrations of the A chains. Polymer reference interaction site model (PRISM) calculations were performed on this same blend and very good agreement was found between the theory and the simulation over a range of compositions, Significant nonrandom mixing was observed from the molecular dynamics simulations on local length scales; PRISM theory was able to accurately predict these nonrandom local features in the packing.

The TGA and interface recession measurements both gave linear reaction kinetics for O-2 concentrations of 2.0% or less and a reaction order of unity. Subcritical crack growth measurements demonstrated that the crack velocity, in the stress-intensity-independent stage II regime, increases with increasing O-2/Ar ratio. Also, the transition from stage II to the stress-intensity-dependent stage III regime is shifted to lower stress intensities with increasing O-2/Ar ratio. A time-dependent crack growth model that incorporates creep of the bridging SIC fibers and the removal of the C interfacial layer by oxidation successfully explains the subcritical crack growth characteristics.

AB A 45 x 45 mm rectangular silicon drift detector (SDD) was irradiated using a Co-60 gamma-source and its performance was studied. The total integrated dosage was 9 krad which is equivalent to the ionizing radiation dosage that the STAR SVT inner barrel detectors are expected to receive during 10 years of running at the soon to be built RHIC collider. The detector's performance after a high temperature annealing was also studied. The detector was found to be sufficiently radiation hard for RHIC applications.

AB A superconducting kaon spectrometer has been installed in the north experimental hall of the KEK 12-GeV proton synchrotron. The spectrometer was designed to serve for nuclear physics experiments with meson beams in the 1 GeV/c region, particular emphasis being laid on study of Lambda-hypernuclei via (pi(+),K+) reactions. In order to obtain h-hypernuclear data with better statistics and energy resolution, it was designed to have a good momentum resolution of 0.1% FWHM and a large acceptance of 100 msr. It consists of a large superconducting dipole magnet, tracking chambers, and trigger counters that can efficiently select kaons from large background of pions and protons. The overall energy resolution for scattering is realized together with a beam-line spectrometer in the K6 beam line, the momentum resolution of which was also designed to be better than 0.1% FWHM. A good energy resolution of better than 2 MeV FWHM has been confirmed in pi(-)-C-12 elastic scattering and in the (pi(+),K+) reaction on C-12.

AB We have measured the differential optical reflectivity (lambda = 0.78 mm) of YBa2Cu3O7-x single crystals in the temperature range of 20-300 K using a thermal wave technique. A sharp signal maximum with a temperature width similar to 10 K was observed below T-c, and was attributed to the electronic contribution of the optical reflectivity. It is concluded that the two components of the differential reflectivity signal are related to accumulation of, the superconducting phase and temperature variation of the electron-scattering time.

AB Electromotive-force (EMF) measurements of oxygen fugacities as a function of stoichiometry have been made in the lead-doped Bi-2223 superconducting system in the temperature range 700-815 degrees C by means of an oxygen titration technique that employs an yttria-stabilized zirconia electrolyte. The results of our studies indicate that processing or annealing lead-doped Bi-2223 at temperatures ranging from 750 to 815 degrees C and at oxygen partial pressures ranging from similar to 0.02 to 0.2 atm should preserve Bi-2223 as essentially single-phase material. Thermodynamic assessments of the partial molar quantities Delta ($) over bar S(O-2) and Delta ($) over bar H(O-2) indicate that the plateau regions in the plot of oxygen partial pressure versus oxygen stoichiometry (x) can be represented by the diphasic CuO-Cu2O system. In accord with the EMF measurements, it was found that lead-doped Bi-2223 in a silver sheath is stable at 815 degrees C for oxygen partial pressures between 0.02 and 0.13 atm.

AB The patterns of bifurcation governing the escape of periodically forced oscillations from a potential well over a smooth potential barrier are studied by numerical simulation. Both the generic asymmetric single-well cubic potential and the symmetric twin-well potential Duffing oscillator are surveyed by varying three parameters: forcing frequency, forcing amplitude, and damping coefficient.
The close relationship between optimal escape and nonlinear resonance within the well is confirmed over a wide range of damping, Subtle but significant differences are observed at: higher damping ratios. The possibility of indeterminate outcomes of jumps to and from resonance near optimal escape is completely suppressed above a critical level of the damping ratio (about 0.12 for the asymmetric single-well oscillator). Coincidentally, at almost the same level of damping, the optimal escape condition becomes distinct from the apex in the to, Fl plane of the bistable regime; this corresponds to the appearance of chaotic attractors which subsume both resonant and non-resonant motions within one well. At higher damping levels, further changes occur involving conversions from chaotic-saddle to regular-saddle bifurcations,
These changes in optimal escape phenomena correspond to codimension three bifurcations at exceptional points in the space of three parameters. These bifurcations are described in terms of homoclinic and heteroclinic structures of invariant manifolds, and changes in accessible boundary orbits, The same sequence of codimension three bifurcations is observed in both the twin-well Duffing oscillator and the asymmetric single-well escape equation.
Within the codimension three bifurcation patterns governing escape, one particular codimension two global bifurcation involves a chaotic attractor explosion, or interior crisis, compounded with a blue sky catastrophe or boundary crisis of the exploded attractor, This codimension two bifurcation has structure containing a form of predictive power: knowledge of attractor bifurcations in part of the codimension two pattern permits inference of the attractor and basin bifurcations in the remainder. This predictive power is applicable beyond the context of escape from potential wells,
Quantitative correlation of bifurcation patterns between the two equations according to simple scaling laws is tested.
The unstable periodic orbits which figure most prominently in the major attractor-basin bifurcations are of periods one and three. Their linking is conveniently interpreted by a three-layer spiral horseshoe structure for the folding action in phase space within a well, The structure of this 3-shoe implies a partial ordering among order three subharmonic saddle-node bifurcations, This helps explain the sequence of codimension three bifurcations near optimal escape. Some bifurcational precedence relations are known to follow from the Inking of periodic orbits in a braid on a 3-shoe. Additional bifurcational precedence relations follow from a quantitative property of generic potential wells: the dynamic hilltop saddle has a very large expanding multiplier over one cycle of forcing near fundamental resonance. This quantitative property explains the close coincidence of codimension three bifurcations near the suppression of indeterminate outcomes.
An experimentalist's approach to identifying the three-layer template structure from time series data is discussed, including a consistency check involving Poincare indices.
The bifurcation patterns emerging at higher damping values create favorable conditions for realizing experimental strategies to recognize optimal escape and locate it in parameter space. Strategies based solely on observations of quasi-steady behavior while remaining always within one well are discussed.

Moreover, a predicted multiplet spectrum for the heavy fermion superconductor UPt3 is shown with a calculated Coulomb U of 1.6 eV. These effective Coulomb interactions, which are quite simple to calculate, should be useful inputs to further many-body calculations in correlated electron metals.

AB Scanning-tunneling microscopy has been used to study temperature and coverage dependence of the structure of lead on the Si(111)-7X7 surface. For low Pb coverage, the Pb atoms favored the faulted sites. The ratio between the number of Pb atoms on faulted to unfaulted sites increased after sample annealing. An energy difference of 0.05 eV associated with a Pb atom on these two sites is estimated. The mobility of Pb atoms on Si(111) was observed at a temperature as low as 260 degrees C for a coverage of 0.1 and 1 ML.

AB The time dependence of Schottky-barrier depletion layer charge density is monitored after injection of holes in P- and As-doped Si containing donor/hydrogen pairs. The resultant hole capture event leads to the reactivation of hydrogenated donors. In contrast to the observations of Johnson et al., we see an essentially abrupt change in this capacitance, and little, if any, transient behavior that can be attributed to the sweepout of H+ or the conversion of H- to neutral or positively charged hydrogen. Since we observe that much of the hole-induced charge density disappears after a few days wait under dark conditions, it appears that this reaction is at least partially reversible. We conclude that this experiment provides no direct cofirmation of the existence of positively or negatively charged hydrogen.

AB Different Ag/Si(111) systems have been examined using synchrotron x-ray diffraction. Multi-atomic-layer deposition of Ag onto a Si(111)-(7X7) surface maintained at room temperature results in an unstrained, (111)-oriented film. The interface shows a Ag-modified (7X7) structure which when annealed above 200-250 degrees C transforms to a(1X1) structure. Although this is near the characteristic temperature for formation of the (root (3) over bar X root (3) over bar)R30 degrees surface reconstruction commonly observed for a monolayer of Ag adsorbed on Si(111), no evidence of this (root (3) over bar X root (3) over bar)R30 degrees reconstruction was found at the interface, A Ag monolayer (root (3) over bar X root (3) over bar)R30 degrees surface, further covered by multilayer Ag deposition at room temperature, also shows no indication of the (root (3) over bar X root (3) over bar)R30 degrees reconstruction at the interface. This indicates that the actual interface structure may or may not be related to the clean or adsorbed layer structures. The structure of the Ag-Si interface was further characterized by scans of the crystal truncation rods. Both the (7X7) interface prepared by room-temperature deposition and the annealed (1X1) interface show fairly sharp boundaries. The results suggest some intermixing occurs at the monolayer level for the annealed interface. The structure of the Ag film was also investigated.

AB All-electron, full-potential thin-film calculations with the linear-combination-of-Gaussian-type orbitals-fitting function technique are used to determine the energy required to form an ordered (root (3) over bar X root (3) over bar)R 30 degrees overlayer of Na on the Al(111) surface. Two distinctly different types of adsorption are considered; substitutional adsorption after initial formation of an ordered array of surface vacancies and normal (nonsubstitutional) adsorption at sites with hcp symmetry. The present results for the surface vacancy formation energy, adsorption energies, and adatom-substrate bond lengths are all in good agreement with the results of previous norm-conserving ab initio pseudopotential calculations.

AB Cl+ electron-stimulated desorption energy and angular distributions are collected from Si(111)-7 X 7 surfaces exposed to Cl-2. The results of these measurements are fitted to a model that accounts for variations in the surface work function, ion-surface image-charge interactions, and ion neutralization. From the fits, the strength of the image-charge interaction and the angular dependence of the neutralization are determined. The ideas presented here concerning the motion of ions in the vicinity of a surface are generally valid for ah ion-surface interactions.

DT Article
ID ALKALI-METAL ADSORPTION; CHARGE-TRANSFER; ION-SCATTERING; NEUTRALIZATION
AB Resonant neutralization probabilities for 2 keV Li-7(+) singly scattered from Al and K surface atomic sites are measured from K-covered Al(100). At low K coverages (<0.03 ML), nearly all of the Li+ ions scattered from K are neutralized, while neutral fractions ranging from 32 to 65% are measured for scattering from Al. This indicates that the surface local electrostatic potential is laterally inhomogeneous. At higher K coverages, on the other hand, the neutral fractions for scattering from Al and K become nearly equal, showing that the inhomogeneities are greatly reduced. This represents direct experimental evidence of such a transition.

TI MANY-BODY CALCULATION OF THE MAGNETIC, OPTICAL, AND CHARGE-TRANSFER
SPECTRA OF SOLID OXYGEN IN THE ALPHA-PHASE AND BETA-PHASE
SO PHYSICAL REVIEW B
LA English
DT Article
ID DYNAMICS; ANTIFERROMAGNET
AB The electronic spectra of alpha and beta solid O-2 were calculated in a full many-body approach for a cluster consisting of four O-2 molecules with periodic-boundary conditions. By including only the partially occupied pi orbitals (16 spin orbitals, 8 electrons) the basis set consists of 12 870 many-electron states. The resulting spectra contains three basic types of excitations at very different energy ranges: (a) 81 states corresponding to the ground state and magnetic excitations (magnons) within 100 meV; (b) 1215 states of neutral molecular excitations (excitons) with energies from about 1 to 8 eV; and (c) 11 574 charge-transfer states with excitation energies up to 60 eV. Analysis of the properties of the ground states in both alpha and beta solid O-2 has been carried out. The lowest many-body states, those that correspond to neutral, unexcited molecules, describe accurately the magnetic excitations of both solids. The two phases have very different spectra resulting, even at very low temperatures, in a sizeable difference in the (magnetic) entropy. The calculated entropy difference at the observed alpha-beta phase transition temperature agrees surprisingly well with the experimentally measured heat of transformation.

AB The calculated electronic structure and charge density of UC and US are reported. We also report calculations on the elastic constants of the cubic compounds UC, US, and UTe using the local-spin-density approximation (LSDA) to the exchange and correlation potential. Good agreement between calculations and experiment has been obtained for UC and US suggesting that the chemical bonding is well reproduced by LSDA for these two compounds. In contrast, for UTe the calculations do not reproduce the measured negative Poissons ratio (negative C-12). We suggest that the failure to describe the elasticity of UTe reflects the weakness of LSDA in describing accurately electron systems that are strongly correlated and we speculate that UTe is an anomalous, possibly mixed valent, system.

ID QUANTUM-WELL STRUCTURES; GAAS-ALAS SUPERLATTICES; TRANSPORT; TIME
AB We have measured the time- and space-resolved evolution of type-II excitons in GaAs/AlAs superlattices with various AlAs layer thicknesses, at temperatures ranging from 1.8 to 30 K. Our photoluminescence (PL) time decay and transport results demonstrate that the exciton-decay kinetics at low temperatures are entirely determined by intrinsic radiative recombination, whereas at higher temperatures, the PL time decays are dominated by nonradiative defect trapping processes. We show that these nonradiative decays do not occur within the layers but are instead localized at the heterointerfaces. The measured lifetimes at 30 K are consistent with our model calculations based on this interpretation. Furthermore, the superlattice and interface-disorder-induced Gamma-X mixing potentials are determined from our low-temperature exciton lifetimes to be 1.3 and 0.2 meV, respectively.

AB Properties of polymeric fullerenes are studied theoretically using a semiempirical model that treats only the pi electrons explicitly but allows for lattice relaxations. Both neutral and charged systems are studied, and both the isolated C-60 molecule as well as the polymer. In agreement with experiments, the model predicts the elongation of certain intraball bonds upon polymerization as the most significant structural relaxation. This is found both for the neutral and the charged system. For the latter, we observe symmetry reductions, and it is suggested that polaronlike distortions or charge-density waves may act as charge carriers. The distortions are predicted to induce extra phonon modes that should be observable experimentally.

AB A high-order multiple-scattering (MS) approach to the calculation of polarized x-ray-absorption spectra, which includes both x-ray-absorption fine structure and x-ray-absorption near-edge structure, is presented. Efficient calculations in arbitrary systems are carried out by using a curved-wave MS path formalism that ignores negligible paths, and has an energy-dependent self-energy and MS Debye-Waller factors. Embedded-atom background absorption calculations on an absolute energy scale are included. The theory is illustrated for metallic Cu, Cd, and Pt. For these cases the MS expansion is found to converge to within typical experimental accuracy, both to experiment and to full MS theories (e.g., band structure), by using only a few dozen important paths, which are primarily single-scattering, focusing, linear, and triangular.

AB We present a useful formalism for the calculation of the polarizability and dielectric response of periodic systems. Our approach is to introduce intermediate ''mixed-space'' functions with the full translational periodicity of the lattice. This is a considerable advantage over existing real-space methods since the decay length of a response function [such as epsilon(r,r'\omega)] can be significantly larger than the Wigner-Seitz cell radius. Further, we show that, in supercell calculations, these mixed-space functions decay as fast as the corresponding real-space quantities within one supercell, so that the present scheme can be combined with usual real-space cutoff techniques. The advantage of the present method compared to a standard reciprocal space approach is exemplified for the case of bulk silicon and for the case of a Si surface in a slab geometry.

SO PHYSICAL REVIEW D
LA English
DT Article
ID SOLAR MODELS; NEUTRINO
AB A derivation of screening effects in a moderately dense equilibrated plasma, based on the methods of finite-temperature field theory, demonstrates the limits of validity of the ''weak screening'' form. Because the systematics of the theory make it possible to unambiguously separate off the leading order e(3) there can be no effects that cancel screening. The static nature of the equilibrium removes questions connected with use of time-response methods for a steady-state problem. The derived screening potential approaches the Debye-Huckel potential at large separations, but is cut off by quantum effects at short distances; the inherent violations of self-consistency in classical derivations of the Debye-Huckel potential are absent. Applied to the conditions of the Sun's central region, screening corrections deviate only moderately from the classical, similar to 15%. The partial degeneracy of electrons also presents only small effects beyond those accounted for by the appropriate population factors. Given the weak role of screening, the effect of the corrections on solar neutrino fluxes is, therefore, seen to be small.

ID GOLDSTONE FERMIONS; GAUGE-THEORIES; SIGMA-MODELS; BREAKING
AB We consider the structure of effective Lagrangians describing the low-energy dynamics of supersymmetric theories in which a global symmetry G is spontaneously broken to a subgroup H while supersymmetry is unbroken. In accordance with the supersymmetric Goldstone theorem, these Lagrangians contain Nambu-Goldstone superfields associated with a coset space G(c)/($) over cap H, where G(c) is the complexification of G and ($) over cap H is the largest subgroup of G(c) that leaves the order parameter invariant. The Lagrangian may also contain additional light matter fields. To analyze the effective Lagrangian for the matter fields we first consider the case where the effective Lagrangian is obtained by integrating out heavy modes at weak coupling (but including nonperturbative effects such as instantons). We show that the superpotential of the matter fields is H invariant, which can give rise to nontrivial relations among independent H invariants in the superpotential. We also show that the Kahler potential of the matter fields can be restricted by a remnant of ($) over cap H symmetry. These results are nonperturbative and have a simple group-theoretic interpretation. When we relax the weak-coupling constraint, there appear to be additional possibilities for the action of a on the matter fields, hinting that the constraints imposed by ($) over cap H may be even richer in strongly coupled theories.

AB A generating functional F is found for a canonical non-Abelian dual transformation which maps the supersymmetric chiral O(4) sigma model to an equivalent supersymmetric extension of the dual sigma model. This F produces a mapping between the classical phase spaces of the two theories in which the bosonic (coordinate) fields transform nonlocally, the fermions undergo a local tangent space chiral rotation, and all currents (fermionic and bosonic) mix locally. Purely bosonic; curvature-free currents of the chiral model become a symphysis of purely bosonic and fermion bilinear currents of the dual theory. The corresponding transformation functional T which relates wave functions in the two quantum theories is argued to be exactly given by T = exp(iF).

AB Background: Cytochrome c is an integral part of the mitochondrial respiratory chain. It is confined to the intermembrane space of mitochondria, and has the function of transferring electrons between its redox partners. Solution studies of cytochrome c indicate that the conformation of the molecule is sensitive to the ionic strength of the medium.
Results: The crystal structures of cytochromes c from several species have been solved at extremely high ionic strengths of near-saturated solutions of ammonium sulfate. Here we present the first crystal structure of ferricytochrome c at low ionic strength refined at 2.1 Angstrom resolution. In general, the structure has the same features as those determined earlier. However, there are some differences in both backbone and side-chain conformations in several areas. These areas coincide with those observed by NMR and resonance Raman spectroscopy to be sensitive to ionic strength.
Conclusions: Neither ionic strength nor crystal-packing interactions have much influence on the conformation of horse cytochrome c. Nevertheless, some differences in the side-chain conformations at high and low ionic strengths may be important for understanding how the protein functions. Close examination of the gamma-turn (residues 27-29) conserved in cytochromes c leads us to propose the 'negative classical' gamma-turn to describe this unusual feature.

ID GERMANIUM; FOIL; SPECTRA
AB Time- and two-dimensional spatially-resolved monochromatic imaging is performed on Ne-like germanium laser-produced line plasmas to study the behaviour of the inhomogeneities along the line created by a nonuniform irradiation. The imaging is done at the wavelengths of the 2s2p(6)3d-2s(2)2p(6)(J=2-0) E2 quadrupole line (lambda=8.031 Angstrom) and the 2s2p(6)3p-2s(2)2p(6)(J=1-0) 3A dipole line (lambda=8.371 Angstrom) which originate respectively from the upper and lower states of the core-excited 3d-3p x-ray laser line at 199 Angstrom. We compare the E2 and 3A results to LASNEX hydrodynamics and associated atomic physics, and investigate the problem of extracting the 3d-3p local gain dynamics along the inhomogeneous line plasma from spectroscopic imaging of the plasma. The effect of the irradiation uniformity conditions on the integrated lasing intensity is discussed.

AB Spin-echo and free induction decay (FID) detected electron paramagnetic resonance were applied to detect free D atoms in the pulse radiolysis of CD4 in liquid argon, krypton, xenon, and nitrogen at 77-160 K. The D atoms were polarized through chemically induced dynamic electron polarization in random encounters. The decay of polarization was essentially independent of the fraction of methane (1-70 mol %) and the temperature of the liquid solution. Analysis of the polarization decay kinetics and the D atoms yield suggests that ion reactions dominate over energy transfer reactions in these mixtures (except for xenon solutions). In solid CD4-Ar mixtures a satellite resonance line of unusually polarized D atoms was observed. This indicates microheterogeneous nature of these solid mixtures and explains anomalous chemistry observed in the media.

ID NUCLEI
AB The recently discovered superdeformed band in one of the strontium isotopes has been identified as belonging to Sr-83 from a study with the Gammasphere array and the Microball charged-particle detector system. From its decay pattern, a spin of (81 +/- 2)/2 ($) over bar h is deduced for the highest level of this band. Evidence for very fast transition rates and agreement of the characteristics of this band with the theoretical predictions establish the yrast superdeformed nature of this band in Sr-83.

AB Photoproduction at HERA is studied in ep collisions, with the ZEUS detector, for yp centre-of-mass energies ranging from 130-270 GeV. A sample of events with two high-p(T) jets (p(T) > 6 GeV, eta < 1.6) and a third cluster in the approximate direction of the electron beam is isolated using a clustering algorithm. These events are mostly due to resolved photoproduction. The third duster is identified as the photon remnant, Its properties, such as the transverse and longitudinal energy flows around the axis of the cluster, are consistent with those commonly attributed to jets, and in particular with those found for the two jets in these events. The mean value of the photon remnant p(T) with respect to the beam axis is measured to be 2.1 +/- 0.2 GeV, which demonstrates substantial mean transverse momenta for the photon remnant.

AB We have used two-dimensional H-1 NMR spectroscopy to determine the solution structure of the DNA oligonucleotide d(5'-CGCTAGCG-3')2 complexed with the bis-intercalating dye 1.1'-(4.4.8.8-tetramethyl-4,8-diazaundecamethylene)bis 1,3-thiazolyl-2-methlidene)qui nolinium] tetraiodide (TOTO), The determination of the structure was based on total relaxation matrix analysis of the NOESY cross-peak intensities using the program MARDIGRAS. Improved procedures to consider the experimental ''noise'' in NOESY spectra during these calculations have been employed. The NOE-derived distance restraints were applied in restrained molecular dynamics calculations. Twenty final structures each were generated for the TOTO complex from both A-form and B-form dsDNA starting structures, The root-mean-square (rms) deviation of the coordinates for the 40 structures of the complex was 1,45 Angstrom. The local DNA structure is distorted in the complex. The helix is unwound by 60 degrees and has an overall helical repeat of 12 base pairs, caused by bis-intercalation of TOTO, The poly(propylenamine) linker chain is located in the minor groove of dsDNA. Calculations indicate that the benzothiazole ring system is twisted relative to the quinoline in the uncomplexed TOTO molecule. The site selectivity of TOTO for the CTAG-CTAG site is explained by its ability to adapt to the base pair propeller twist of dsDNA to optimize stacking and the hydrophobic interaction between the thymidine methyl group and the benzothiazole ring. There is a 3000-fold fluorescence enhancement upon binding of TOTO to dsDNA. Rotation about the cyanine methine bonds is possible in free TOTO, allowing relaxation nonradiatively. When bound to dsDNA, the benzothiazole ring and the quinolinium ring are clamped by the nucleobases preventing this rotation, and the chromophore loses excitation energy by fluorescence instead.

AB The oxidized and reduced forms of the (4Fe-4S]-containing ferredoxin from the hyperthermophilic archaeon Pyrococcus furiosus, Pf, have been investigated by H-1 nuclear magnetic resonance spectroscopy, electron paramagnetic resonance spectroscopy and thiol titrations. We have identified and isolated at ambient temperature four distinct redox states for the [4Fe-4S] form of the ferredoxin. These states differ in the redox state of the cluster, which is coordinated by Cys 11, Asp 14, Cys 17, and Cys 56, and of a disulfide bridge between Cys 21 and Cys 48, The protein, as isolated under anaerobic conditions, designated 4Fe Fd(B)(red), contains the reduced cluster and two free thiols. The cluster, but not the thiols, is readily oxidized by brief exposure to O-2 to yield 4Fe Fd(B)(ox). Prolonged O-2 treatment (> 24 h at 30 degrees C) is required to generate the protein with a disulfide (4Fe Fd(A)(ox)) while this fully oxidized form is readily converted by brief reduction with sodium dithionite to the protein with a reduced cluster and a disulfide (4Fe Fd(A)(red)), Analyses of the magnitude and the number of hyperfine-shifted resonances in each of the four redox states are discussed.

AB The radio galaxy Fornax A is well known for its giant radio lobes which extend almost a degree (similar to 300 kpc) across the sky. Fomalont et al, have shown that these lobes are linearly polarized on the largest scales, although the western lobe is highly depolarized in discrete, resolved regions. The depolarized regions indicate the presence of ionized gas (Faraday screen) along the line of sight to the western lobe. We have now detected the warm gas at H alpha using a Fabry-Perot interferometer in a way that allows us to reach very low surface brightness levels (<10(-19) erg cm(-2) s(-1) arcsec(-2)). The radial velocity of the ionized gas (1610 km s(-1)) places it in the Fornax cluster at a projected radius of 1.0 Mpc, The gas is spread over a region 10 kpc in diameter and has an ionized mass of 6 x 10(7) f(-0.5) M. (where f is the volume filling factor). For the inferred column density of electrons (approximate to 2.6 x 10(20) f(-0.5) cm(-2)) and in light of the H I upper limits (<4 x 10(19) cm(-2)), the cloud has to be mostly ionized. Possible sources of ionization are large-scale shocks or a putative hot component which confines the radio lobes. The high line-of-sight magnetic field strength (B-parallel to approximate to 0.3-1.3 mu G) deduced from the rotation measure (approximate to 20 rad m(-2)) and energy equipartition suggests that the cloud may have undergone significant turbulent heating from secondary shocks. The predicted bounds on the fraction of neutral material (10(-6)-10(-1)) indicates that this may be the first example of a spatially resolved, extragalactic ionized cloud. Such objects are thought to be responsible for some of the Ly alpha absorption lines observed in the spectra of quasars.

AB We consider (AlAs)(n)/(GaAs)(n) superlattices with random thickness fluctuations Delta n around the nominal period n. Using three-dimensional pseudopotential plane-wave band theory, we show that i) any amount Delta n/n of thickness fluctuations leads to band edge wave function localization, ii) for small Delta n/n the SL band gap is pinned at the gap level produced by a single layer with <
