The half-life of the fission activity was measured to be 144+/-5 seconds. The mass-yield distribution is predominantly asymmetric and the most probable preneutron emission total kinetic energy of fission is 179+/-7 MeV. The ECDF mode in Bk-238 was verified by an x-ray-fission coincidence experiment which indicated that the Cm-238 fission lifetime is between about 10(-15) and 10(-9) seconds. The isotope was assigned to Bk-238 through chemical separation and observation of the known 2.4-h Cm-238 daughter activity. No alpha branch was observed in the decay of Bk-238. The production cross section for Bk-238 is 150+/-20 nb and the delayed fission probability is (4.8+/-2) X 10(-4). C1 UNIV CALIF BERKELEY,DEPT CHEM,BERKELEY,CA 94720.

Transitions from the noncollective oblate (gamma = +60-degrees) state associated with band termination and from the collective oblate (gamma = -60-degrees) band head to prolate states have been observed to be significantly hindered; mean lifetimes of tau = (379 +/- 32) ps for the 39/2- state at 5433 keV and tau = (83 +/- 17) ps for the 11/2- state at 1327 keV, respectively, have been measured. In addition, a mean lifetime of tau = (273 +/- 10) ps was determined for the 11/2- state at 811 keV. C1 BROOKHAVEN NATL LAB,DEPT PHYS,UPTON,NY 11973.

While most recognized for its symmetries and algebraic structure, the model has a number of other less-well-known but equally intrinsic properties which give unavoidable, parameter-free predictions. Since these predictions cannot be altered and since they concern central aspects of low-energy nuclear collective structure, they provide a set of basic tests of the inherent framework of the model. This paper outlines these ''robust'' predictions and compares them with the data. C1 CLARK UNIV,WORCESTER,MA 01610. UNIV COLOGNE,INST KERNPHYS,D-50937 COLOGNE,GERMANY.

In view of this discrepancy the present work was undertaken to check the experimental cross sections for 0.76 GeV/nucleon La + La collisions using a small-acceptance magnetic spectrometer. The 20-degrees cross sections were determined by measuring the appropriate range of polar laboratory angles and momenta which, when transformed into the projectile frame, produce the cross sections at 20-degrees. Cross sections have been determined from 30-degrees to 75-degrees for protons and light nuclei with rigidities from 0.5 to 2.0 GeV/c in the laboratory frame. Cross sections were also deduced at 15-degrees and 20-degrees in the projectile frame for nucleon momenta from 0.9 to 1.5 GeV/c. The original experimental results for the larger polar laboratory angles (40-degrees and 60-degrees) were confirmed; however, the 20-degrees cross sections disagree by a factor of about 1.5 (approximately 2sigma). At large polar laboratory angles (40-degrees-70-degrees) the model calculations disagrees in the low-momentum range with the present data by a factor of 1.5 (approximately 3sigma). The discrepancy at small polar angles (15-degrees and 20-degrees) has been significantly reduced from the original factor of 2.5 down to a value of 1.2 (approximately 3sigma).

We find this claim to be confusing, because the prescription used for knockon exchange differs from that usually regarded as part of the M3Y model, and unjustified because we find that the optimum fits to the data do require a reduction of about 30% in the strength of the M3Y interaction. The use of the M3Y model is reviewed briefly. C1 UNIV GEORGIA,ATHENS,GA 30602. RP SATCHLER, GR (reprint author), OAK RIDGE NATL LAB,OAK RIDGE,TN 37831, USA.

The strength of this decay channel has important implications for the production rate of C-12 in stellar nucleosynthesis.

An antiproton that passes through the Coulomb field of a nucleus of charge Z will create e+e- pairs, and antihydrogen will form when a positron is created in a bound rather than a continuum state about the antiproton. The cross section for this process is calculated to be approximately 4Z2 pb for antiproton momenta above 6 GeV/c. The gas target of Fermilab Accumulator experiment E760 has already produced approximately 34 unobserved antihydrogen atoms, and a sample of approximately 760 is expected in 1995 from the successive experiment E835. No other source of antihydrogen exists. A simple method for detecting relativistic antihydrogen is proposed and method outlined of measuring the antihydrogen Lamb shift to approximately 1 %.

We use ISAJET 7.03 to simulate charged slepton and sneutrino pair production, incorporating slepton and sneutrino cascade decays into our analysis. We find that even with an accumulation of approximately 1 fb-1 of integrated luminosity, it will be very difficult to detect sleptons beyond the reach of CERN LEP at the Fermilab Tevatron ppBAR collider, due to a large background from W pair production. We confirm that at CERN LHC, sleptons of mass up to 300 GeV ought to be detectable via the dilepton signal as long as it is possible to veto central jets with p(T) greater-than-or-equal-to 25 GeV with high efficiency.

The jet definition scheme is based on a modified JADE cluster algorithm. The calculation of the (2+1) jet cross section is described in detail. Results for the virtual corrections as well as for the real initial- and final-state corrections are given explicitly. Numerical results are stated for jet cross sections as well as for the ratio sigma(2+1)jet/sigma(tot) that can be expected at E665 and DESY HERA. Furthermore the scale ambiguity of the calculated jet cross sections is studied and different parton density parametrizations are compared.

In particular, we consider the question of whether a net polarization of the initial heavy quark may be detected, either in a polarization of the final ground state or in anisotropies in the decay products of the excited hadron. The result hinges in part on a nonperturbative parameter which measures the net transverse alignment of the light degrees of freedom in the fragmentation process. We use existing data on charmed mesons to extract this quantity for certain excited mesons. Using this result we estimate the polarization retention of charm and bottom baryons.

These methods select one Higgs-boson decay mode above all others with high purity, leaving measurable standard model backgrounds as the only source of contamination. Integrated luminosities of 50 fb-1 are required to obtain statistical errors of 10-20% on the branching fractions to bbBAR, tau+tau-, and WW(*). For an intermediate-mass Higgs boson this is sufficient to distinguish the minimal supersymmetric standard model Higgs boson from the standard model Higgs boson over most of the supersymmetric parameter space.

Most of our work is with four time slices, although we include some runs with six and eight time slices for comparison. In addition to the usual themodynamic observables, we study the quark mass defined by the divergence of the axial vector current and the quark propagator in the Landau gauge.

In particular we consider the dynamics of the charged states associated with rotational excitations of the soliton in the internal space and their interactions with the quanta of the background field (mesons). By solving a system of coupled saddle-point equations we effectively sum all tree graphs contributing to the one-point Green's function of the meson field in the background of a rotating soliton. We find that the resulting one-point function evaluated between soliton states of definite U(1) charge exhibits a pole on the meson mass shell and we extract the corresponding S-matrix element for the decay of an excited state via the emission of a single meson using the standard Lehmann-Symanzik-Zimmermann reduction formula. This S-matrix element has a natural interpretation in terms of an effective Lagrangian for the charged soliton states with an explicit Yukawa coupling to the meson field. We calculate the leading-order semiclassical decay width of the excited soliton states and discuss the consequences of these results for the hadronic decay of the DELTA resonance in the Skyrme model.

Combining SO(10) grand unification, family symmetries and supersymmetry with a systematic operator analysis, the minimal set of fermion mass operators consistent with low-energy data is determined. Exploiting the full power of SO(10) to relate up, down, and charged lepton mass matrices, we obtain predictions for seven of the mass and mixing parameters. The assumptions upon which the operator search and resulting predictions are based are stressed, together with a discussion of how the predictions are affected by a relaxation of some of the assumptions. The masses of the heaviest generation, m(t), m(b), and m(tau), are generated from a single renormalizable Yukawa interaction, while the lighter masses and the mixing angles are generated by nonrenormalizable operators of the grand unified theory. The hierarchy of masses and mixing angles is thereby related to the ratio of grand to Planck scales, M(G)/M(P). An explicit realization of the origin of such an economical pattern of operators is given in terms of a set of spontaneously broken family symmetries. In the preferred models the top quark is found to be heavy, M(t) = 180 +/- 15 GeV, and tanbeta is predicted to be very large. Predictions are also given for m(s), m(s)/m(d), m(u)/m(d), V(cb), V(ub)/V(cb) and the amount of CP violation. Stringent tests of these theories will be achieved by more precise measurements of M(t), V(cb), alpha(s), and V(ub)/V(cb) and by measurements of CP violation in neutral B meson decays.

At nonzero temperature and baryon density it is expected that in the chiral limit the chiral phase transition is of first order. Increasing the quark mass from zero, the chiral transition becomes more weakly first order, and can end in a chiral critical point. We show that the only massless field at the chiral critical point is a sigma meson, with the universality class that of the Ising model.

Shan and H. Chen, Phys. Rev. E47, 1815 (1993)] for simulating flows with multiple phases and components. In particular, the focus is on the modeling of one-component fluid systems which obey nonideal gas equations of state and can undergo a liquid-gas-type phase transition. The model is shown to be momentum conserving. From the microscopic mechanical stability condition, the densities in bulk liquid and gas phases are obtained as functions of a temperaturelike parameter. Comparisons with the thermodynamic theory of phase transitions show that the lattice-Boltzmann-equation model can be made to correspond exactly to an isothermal process. The density profile in the liquid-gas interface is also obtained as a function of the temperaturelike parameter and is shown to be isotropic. The surface tension, which can be changed independently, is calculated. The analytical conclusions are verified by numerical simulations. C1 DARTMOUTH COLL,DEPT PHYS & ASTRON,HANOVER,NH 03755.

We present a modified version of the Bird algorithm in which the relaxation processes are enhanced and the transport coefficients reduced, while preserving the correct equilibrium and nonequilibrium fluid properties.

The observed glass leach rates decrease as the ionic strength of the leachant increases. These results suggest that this effect is not due to the thermodynamic ionic strength, as explained previously, but rather to a kinetic ion exchange process between the salt solutions and the glass. We suggest that kinetic ion exchange processes affect glass dissolution by suppressing destructive hydronium/alkali exchange and facilitating the competing nondestructive alkali in solution/alkali on glass exchange. This mechanism is supported by data on cation size, solution pH and salt concentration and by thermodynamic calculations using a geochemical computer code, PHREEQE. Identification of the predominant mechanism is important in accounting for the salt effects in models being developed to predict the behaviour of nuclear waste glasses in geologic repositories.

The method employs two weight functions to evolve deltaf in phase space. It is valid for quite general, non-Hamiltonian dynamics with arbitrary sources. In the absence of sources, only one weight function is required and the scheme reduces to the nonlinear algorithm developed by Parker and Lee [Phys. Fluids B 5, 77 (1993)] for sourceless simulations. (It is shown that their original restriction to Hamiltonian dynamics is unnecessary.) One-dimensional gyrokinetic simulations are performed to show the utility of this two-weight scheme. A systematic kinetic theory is developed for the sampling noise due to a finite number of marker trajectories. The noise intensity is proportional to the square of an effective charge q(eff)=q(omegaBAR/D), where omegaBAR approximately deltaf/f is a typical weight and D is the dielectric response function.

The soil (+/-50 pellets) was infested with egg masses or cysts when placed into cups on day 0 or with juveniles on day 14. Seedlings were planted on day 17, and roots were measured and stained on day 22. The fungus always was more effective in soil infested with juveniles than in soil infested with egg masses or cysts, but substantial variability among trials within experiments limited our quantitative inferences. Suppression of nematodes per centimeter of root averaged 42 or 98% in soil infested with egg masses or juveniles of M. javanica and 83 or 98% in soil infested with cysts or juveniles of H. schachtii. Hirsutella rhossiliensis did not suppress M. javanica in egg mass-infested loamy sand when nematode density, as determined by bioassay, exceeded 1,200/100 cm(3) of soil but suppressed H. schachtii in cyst-infested loamy sand and loam regardless of nematode density.

We have been interested in the signal transduction pathway responsible for symbiotic, temporal and spatial control of expression of an early (Enod2) and a late (Leghemoglobin; lb) nodulin gene from the stem-nodulated legume Sesbania rostrata, and in identifying the cis-acting elements and trans-acting factors involved in this process (De Bruijn and Schell, 1992). By introducing chimeric S. rostrata lb promoter-gus reporter gene fusions into transgenic Lotus corniculatus plants, we have been able to show that the lb promoter directs an infected-cell-specific expression pattern in Lotus nodules. We have been able to delimit the cis-acting element responsible for nodule-infected-cell-expression to a 78 bp region of the lb promoter (NICE Element) and have analyzed this element in detail by site-specific mutagenesis. We have studied the interaction of the NICE element, and further upstream cis-acting elements, with trans-acting factors of both plant- and rhizobial origin. We have obtained evidence for the involvement of rhizobial proteins in infected-cell-specific plant gene expression (Welters et al.,1993). We have purified one of the bacterial binding proteins from the S. rostrata symbiont Azorhizobium caubinodans (AcBBP1), and cloned and mutated the corresponding gene, in order to examine its symbiotic phenotype. We have also found that the S. rostrata Enod2 gene is rapidly induced by physiologically significant concentrations of cytokinins, suggesting the role of cytokinin as a potential secondary signal involved in nodulation (Dehio and De Bruijn, 1992). We are examining whether the observed cytokinin induction, as well as the nodule-specific expression pattern, are modulated by the SrEnod2 promoter.

Starting materials, virgin and final colored formulation were studied. Analysis revealed polymorphic impurity at all stages of production and processing, the nature and concentration of which changed with treatment of the material. Thermally-induced polymorphic conversion was determined to be the cause of the decrease in density, whereas the color change was speculated to be the result of binder degradation. Sensitivity to impact, friction and electrostatic spark were unchanged. RP FOLTZ, MF (reprint author), LAWRENCE LIVERMORE NATL LAB,LIVERMORE,CA 94550, USA.

This work had indicated that localized material processing occurs during the earliest stages of liner collapse and causes dramatic visible grain size refinement, evident in the photomicrographs. Further computational analysis shows that the localized plastic flow is accompanied by very high localized engineering strains (> 200), extremely high (> 4 x 10(7) s(-1)) localized strain rates, as well as elevated temperatures, all of which favor a dynamic recrystallization process((3)). In this paper, the focus is on a detailed quantitative analysis of strain, strain rate and temperature distribution history within the collapsing liner, in the region of the inner liner apex and the early location of the moving collision zone, where the early material conditioning first occurs. Correlations are sought between the computed, time-dependent values of these three parameters and the microstructures observed in the interiors of the partially collapsed liners, in those regions where the grain size changes are observed. This data may ultimately permit quantitative comparisons with the predictions of dynamic recrystallization models((3)). C1 LOS ALAMOS NATL LAB,LOS ALAMOS,NM 87545.

In the original method (Bowie JU, Luthy R, Eisenberg D, 1991, Science 253:164-170), residue environments were quantized into 18 discrete environmental classes. Here, amino acid residue preferences are expressed as a continuous function of environmental variables (residue area buried and fractional area buried by polar atoms). This continuous representation of residue preferences, expressed as a Fourier series, avoids the abrupt change of preference of residues in slightly different environments, as encountered in the original method with its 18 discrete environmental classes. When compared with the discrete 18-class representation of residue environments, this continuous 3D profile is found to be more sensitive in identifying sequences that fold into the profiled structure but share with it little sequence identity. The continuous 3D profile is also less sensitive to errors in environmental variables than is the discrete 3D profile. The continuous 3D profile can also be used to detect wrong folds or incorrectly modeled segments in an otherwise correct structure, as could the discrete 3D profile (Luthy R, Bowie JU, Eisenberg D, 1992, Nature 356:83-85). Moreover, the progress of structure improvement during atomic refinement can also be monitored by examining the profile scores in a moving-window scan. Finally, by defining a functional form for profile scores, we open the way to profile atomic refinement in which an atomic structure adjusts to produce residue environments more compatible with the protein side chains.

WR-1065 is an effective radiation protector when it is administered 30 min prior to exposure of Chinese hamster ovary K1 cells to radiation (i.e., a dose modification factor of 1.4) at a concentration of 4 mM. Under these exposure conditions, topoisomerase (Topo) I and II alpha activities and associated protein contents-were measured in cells of the K1 cell line using the DNA relaxation assay, the P4 unknotting assay and immunoblotting, respectively. WR-1065 was ineffective in modifying Topo I activity, but it did reduce Topo II alpha activity by an average of 50%. The magnitude of Topo II alpha protein content, however, was not affected by these exposure conditions. The effects on the cell cycle were monitored by the method of flow cytometry. Exposure of cells to 4 mM WR-1065 for up to 6 h resulted in a build-up of cells in the G(2)/M-phase compartment. However, under these conditions and in contrast to Topo II inhibitors used in chemotherapy, WR-1065 is an effective radioprotective agent capable of protecting against both radiation-induced cell lethality and mutagenesis. One of several mechanisms of action attributed to aminothiol compounds such as WR-1065 has been their ability to affect endogenous enzymatic reactions involved in DNA synthesis and repair and progression of cells through the phases of the cell cycle. These results are consistent with such a proposed mechanism and demonstrate in particular a modifying effect by WR-1065 on Topo II, which is involved in DNA synthesis.

In vitro studies have shown that differences in the radiation sensitivity of squamous cell carcinoma cell lines reflect alterations in DNA repair. These alterations result from constitutive changes in chromosome organization, not radiation-inducible processes. While inducible responses may play some role in the radiation response of tumor cells, there is no evidence for their involvement in inherent differences in tumor cell radiosensitivity or in the success or failure of radiotherapy of squamous cell carcinomas.

Our past work had shown similar modulation of transcripts for alpha-tubulin, beta- and gamma-actins, ornithine decarboxylase and interleukin 1 after exposure to either neutrons or gamma rays. However, differences in the expression of beta-protein kinase C and c-fos genes were observed, with both being induced after exposure to gamma rays but not neutrons. Recently we have identified two genes that are induced after exposure to neutrons but not gamma rays: Rp-8 (a gene associated with apoptosis) and the long terminal repeat (LTR) of the human immunodeficiency virus (HIV). Induction of Rp-8 mRNA was demonstrated in Syrian hamster embryo (SHE) fibroblasts and was found to be induced in cells exposed to neutrons administered at low(0.005 Gy/min) and high dose rate (0.12 Gy/min). No induction of other genes associated with apoptosis such as Rp-2, bcl-2 and Tcl-30 was observed. The induction of transcription from the LTR of HIV was demonstrated in HeLa cells bearing a transfected construct of the chloramphenicol acetyl transferase (CAT) gene driven by the HIV-LTR promoter. Measurements of CAT activity and CAT transcripts after irradiation demonstrated an unresponsiveness to gamma rays over a broad range of doses (0.1-3 Gy). Twofold induction of the HIV-LTR was detected after exposure to neutrons (0.48 Gy) administered at low (0.05 Gy/min) but not high (0.12 Gy/min) dose rates. Ultraviolet-mediated HIV-LTR induction, however, was inhibited by exposure to few-dose-rate neutron irradiation. These results are interesting in light of reports that Rp-8 is induced during apoptosis and that HIV causes apoptosis. C1 LOYOLA UNIV,DEPT PATHOL,MAYWOOD,IL 60153.

The advanced concept design uses a minimum-B magnetic mirror geometry which consists of a multicusp magnetic field to assist in confining the plasma radially, a flat central field for tuning to the ECR resonant condition, and specially tailored mirror fields in the end zones to confine the plasma in the axial direction. The magnetic field is designed to achieve an axially symmetric plasma ''volume'' with constant mod-B, which extends over the length of the central field region. This design, which strongly contrasts with ''surface'' ECR zones characteristic of conventional ECR ion sources, results in dramatic increases in the absorption of rf power, thereby increasing the electron temperature and ''hot'' electron population within the ionization volume of the source. The creation of a volume rather than a surface ECR zone is, therefore, commensurate with the generation of higher beam intensities, higher charge states, and a higher degree of ionization. A summary of the results of these studies is presented in this report. C1 MISSION RES CORP,NEWINGTON,VA 22122. RP ALTON, GD (reprint author), OAK RIDGE NATL LAB,POB 2008,OAK RIDGE,TN 37831, USA.

Realistic array geometries are used and a classical description of spatial resolving power is applied to determine when two separate sources may be resolved. Array parameters such as sensor spacing, coil diameter, and gradiometer type are varied to determine their effect on spatial resolving power. The consequences of the number of sensors is considered and a comparison of existing systems is made. The effects of the vector nature of magnetic sources on spatial resolving power is also considered. It is shown that spatial resolving power is not strongly dependent upon individual sensor diameter, but that sensor spacing is important. It is also found that the instrumental spatial resolving power as a function of depth degrades much more quickly when planar gradiometers are used, as compared to axial gradiometers.

A pulsed NdYaG laser with approximately 25 W average power and peak power density on the order of 10(7) W/cm2 has been used off-line to measure ablation rates of various materials as a function of peak laser power. The benefits anticipated from the successful demonstration of this technique include the ability to use very small quantities of materials efficiently, improved material efficiency of incorporation into the ECR plasma, and decoupling of the material evaporation process from the ECR source tuning operation. The results of these tests are reported herein and the design is described for incorporating such a system directly with the Argonne Tandem Linac Accelerator System Positive Ion Injector ECR (ATLAS PII-ECR) ion source.

The design dc power density on the cathode surface is 900 W/cm2, much higher than achieved in any previously reported Penning surface-plasma source. The source is designed to accommodate dc arc power levels up to 30 kW by cooling the electrode surfaces with pressurized, hot water. After striking the arc using a 600-V pulser, a 350-V dc power supply is switched in to sustain the 100-V discharge. Now our tests are concentrating on arc pulse lengths less-than-or-equal-to 1 s.

Primary applications of this high current metal ion source have evolved for metallurgical ion implantation and for accelerator injection. Novel source versions and features have been developed, including an electronically switchable ''partitioned cathode'' whereby the metal species generated can be switched from pulse to pulse, a combined metal/gaseous source with a long lasting trigger, a low energy (approximately 1 keV) miniature source version, and a broad beam (50 cm diam extractor) multicathode version. Progress has been made also in characterization and manipulation of the plasma prior to extraction, e.g., in the understanding of the ion charge states produced and the development of macroparticle-removing magnetic filters. Advances in vacuum arc ion source design and operation have been accompanied by a deeper understanding of plasma production in vacuum arc cathode spots, and several features of vacuum arc ion sources can be explained by the specifics of ion formation within the spots. Here we present a short overview of some fundamental vacuum arc processes and examine some of the recent developments in vacuum arc ion source design and application.

The ion beam extractor is a three-grid, multiaperture configuration with a low accel-decel ratio so that ions are extracted from the plasma at a relatively high energy and then decelerated to the desired net beam energy. We have tentatively given this ion source the name leva, for low energy vacuum arc ion source. The leva source is cylindrical in shape with diameter about 6 cm and length about 16 cm and is located completely within the vacuum system; it is constructed from metal and alumina only and can be baked. We have operated it at net extraction voltages in the range 0.5-10 kV and produced a titanium ion beam current of up to 120 mA. Here we describe the source construction details and its performance.

Droplet contamination of the substrate can occur when implanting metal ions using a vacuum arc ion source. The contamination can be significant for some cathode materials such as lead and other low melting point metals, which for some ion implantation applications such as for semiconductor doping and metallic corrosion inhibition can be a detriment. We have developed a vacuum arc ion source in which the plasma is filtered before the ions are extracted. By guiding the arc-produced plasma through a 60-degrees bent magnetic duct, macroparticles are completely removed from the plasma. No additional power supply for the guiding magnetic field is required since the pulsed arc current itself is used to drive the magnetic solenoid. Tests have shown that macroparticle-free metal ion implantation can be done while maintaining the high ion beam current typical of vacuum arc ion sources.

This capability was developed within the context of a small angle negative ion source on the Discharge Test Stand at Los Alamos. The controller processes information obtained from the,beam current wave form, developing a figure of merit (fom) to determine the ion source operating conditions. The fom is composed of the magnitude of the beam current, the stability of operation, and the quietness of the beam. Using no knowledge of operating conditions, the controller begins by making of rough scan of the four-dimensional operating surface. This surface uses as independent variables the anode and cathode temperatures, the hydrogen flow rate, and the arc voltage. The dependent variable is the fom described above. Once the rough approximation of the surface has been determined, the network formulates a model from which it determines the best operating point. The controller takes the ion source to that operating point for a reality check. As real data is fed in, the model of the operating surface is updated until the neural network's model agrees with reality. The controller then uses a gradient ascent method to optimize the operation of the ion source. Initial tests of the controller indicate that it is remarkably capable.

Two techniques are discussed, emission spectrosropy and vacuum ultraviolet laser absorption spectroscopy. Time-resolved detection of Balmer-alpha emission has been used to study the excited-state hydrogen atom population. Vacuum ultraviolet laser absorption spectroscopy has been used to measure the ground electronic state atomic and molecular hydrogen populations. The Balmer-alpha emission exhibits a modulation in the intensity at a frequency of twice the exciting rf radiation. On the other hand, the laser absorption measurements show that the density of ground-state hydrogen atoms does not vary significantly with the phase of the exciting rf. Measurements of the vibrational population summed over all rotational states give a vibrational temperature of 6200 K. However, there is no evidence of the ''plateau'' predicted in the distribution for v greater-than-or-equal-to 5. RP YOUNG, AT (reprint author), LAWRENCE BERKELEY LAB,BERKELEY,CA 94720, USA.

The techniques are based on crystal nucleation and growth onto functionalized interfaces. Surface functionalization routes have been developed by the mimicking of schemes used by organisms to produce complex ceramic composites such as teeth, bones, and shells. High-quality, dense polycrystalline films of oxides, hydroxides, and sulfides have now been prepared from ''biomimetic'' synthesis techniques. Ceramic films can be synthesized on plastics and other materials at temperatures below 100-degrees-C. As a low-temperature process in which water rather than organic solvents is used, this synthesis is environmentally benign. Nanocrystalline ceramics can be produced, sometimes with preferred crystallite orientation. The direct deposition of high-resolution patterned films has also been demonstrated. The process is well suited to the production of organic-inorganic composites. RP BUNKER, BC (reprint author), PACIFIC NW LAB, POB 999,BATTELLE BLVD, RICHLAND, WA 99352 USA.

If the temperature on the body is greater than the ambient temperature of the fluid, it is shown that the heat necessary to keep the body temperature fixed is a monotonically increasing function of the how velocity at infinity. When the temperature on the body is everywhere greater than the ambient temperature, but not constant, the authors give a counter example that shows that the above theorem does not apply.

At 5 K between 0 and 4.5 T, the 5 at.% Mg-doped Tl-2212 (Tl, Mg-2212) samples displayed enhanced pinning as demonstrated by a field-dependent increase of the magnetic critical current density J(c) by 18-25% as compared with the pure Tl-2212. Excess Mg (10-15 at.%), however, is deleterious. Rietveld refinement of the x-ray diffraction pattern showed Mg on the Tl sites. AES analysis showed part of the Mg appearing on grain boundaries. Both Tl-2212 and Tl, Mg-2212 displayed a persisting remanent magnetization M(rem) with a higher value for Tl, Mg-2212, as well as an asymmetrical behaviour between flux expulsion and flux penetration. The flux-creep activation energies are higher for flux expulsion than for flux penetration in both samples; Tl, Mg-2212 displayed higher individual values. Our results demonstrate an increase in both intrinsic pinning and lock-in transition of flux lines as a result of increased density of atomic-size structural defects via Mg doping in Tl-2212.

This mechanism primarily involves the adatom and two atoms in the top substrate layer. After passing through the saddle configuration the adatom is found two rows down and one row over from its original position. The movement of the adatom is like that of a knight on a chess board. The activation barrier of this mechanism is high, and it begins to appear at temperatures about half the melting temperature of the material. Due to the long range nature of this mechanism it could significantly affect the adatom diffusion rate as compared to typical hopping between adjacent minima or diffusion via the exchange mechanism.

Changes in synaptic dopamine induced by methylphenidate were evaluated with positron emission tomography and [C-11]raclopride, a D2 receptor radioligand that is sensitive to endogenous dopamine. Methylphenidate significantly decreased striatal [C-11]raclopride binding. The decrease was variable and was negatively correlated with age. Mood and anxiety at baseline, were also correlated with methylphenidate-induced DA changes. This strategy provides a tool to investigate the responsiveness of the dopamine system in the normal and diseased human brain and to investigate the neurochemical correlates of behavior.

Peak heart binding of [C-11]cocaine was high (0.038-0.055%/g) and clearance was rapid (t1/2 from peak: 2.5-9 min) for both tracer doses and a pharmacological dose. The binding of a tracer dose of labeled cocaine could not be inhibited by desipramine, tomoxetine, cocaine, nomifensine, or benztropine. The behavior of a pharmacological dose of [C-11]cocaine could not be distinguished from a tracer dose and also could not be inhibited by tomoxetine. However, pretreatment with cocaine profoundly inhibited norepinephrine uptake as assessed by (-)-6-[F-18]NE. Recovery was slow with only 48% of the baseline (-)-6-[F-18]NE uptake being recovered by 78 minutes after cocaine administration. [C-11]Benzoylecgonine, a vasoactive metabolite of cocaine, showed negligible retention in heart. The results of this study (i.e., the rapid clearance of cocaine from the heart, the inability to inhibit cocaine binding with desipramine and tomoxetine, and its relatively long-lasting effects on norepinephrine uptake) reinforce the need to understand the link between cocaine pharmacokinetics and norepinephrine transporter function and its relationship to cardiotoxicity.

Paleomagnetic data from individual ash flow sheets document no significant relative vertical-axis rotation among localities within central SWNVF, an area of relatively low stratal tilts and widely spaced faults. A time-averaged mean paleomagnetic direction (D = 351.4-degrees, I = 52.7-degrees, alpha95 = 4.5-degrees) calculated from data from numerous separate rock units suggests that the central SWNVF underwent minimal counterclockwise vertical-axis rotation (R = -7.1-degrees +/- 6.6-degrees) with respect to the North American craton. No clockwise vertical-axis rotation is found to support projection of dextral faults of the Walker Lane beneath the central SWNVF. Clockwise rotation of variable magnitude is common at numerous sites from southern and western margins of the field. These clockwise rotations probably reflect dextral shear strain developed at the interface between the little extended central SWNVF block and more strongly extended areas to the south and southwest of the field. Negligible rotation of 11.45-Ma to 13.25-Ma tuffs relative to the central SWNVF was found at the southeast margin of the field where 90-degree4s clockwise rotation at the northwest termination of the Las Vegas Valley shear zone had been postulated. Any clockwise rotation in this area must predate 13.25 Ma, and thus dextral shear within this part of the Walker lane belt was not synchronous or connected across the southern margin of the field.

Our results show that CNN number concentrations (measured at 0.5% supersaturation) and nss SO42- mass concentrations (in the range of approximately 400-1700 ng m-3) are significantly correlated at this site. Droplet concentrations in the cumulus clouds studied do not show a discernible trend with nss SO42- mass concentrations (in the range of approximately 300-1400 ng m-3). In stratocumulus clouds, a small increase in droplet concentration with nss SO42- mass concentrations in the range of approximately 300-1100 ng m-3 was observed. We attribute the low sensitivities of the droplet number concentrations to nss SO42- mass concentrations to the entrainment/mixing processes in these clouds. The magnitudes of the empirically derived sensitivities are considerably lower than those assumed in recent assessments of the effect of anthropogenic sulfate aerosols on cloud albedo.

We also briefly review the kinetics and mechanism of selectivity loss involving tungsten subfluorides. Most kinetic studies of the H-2 + WF6 reaction for typical low pressure CVD conditions report a phenomenological rate law for deposition that is zeroth order in WF6 pressure and 1/2-order in H-2 pressure. Unfortunately, most of the reaction mechanisms reported to yield the observed rate law are inconsistent with the known (or estimated) surface chemical properties of H-2 and WF6 on tungsten. There are also many conditions where the accepted rate law is not valid. For instance, as the H-2 pressure is lowered and becomes comparable with the WF6 pressure, the deposition rate drops to zero. Under these conditions hydrogen chemisorption is apparently completely quenched and the surface is saturated with adsorbed fluorine. Just above the H-2 Pressure threshold the deposition rate is first order rather than 1/2-order with respect to H-2. In this regime the WF6 pressure dependence is also strongly negative order rather than zeroth order. All the deviations from the normal rate law can be qualitatively explained using a Langmuir-Hinshelwood reaction mechanism with competitive adsorption. An important intrinsic mechanism of selectivity loss that occurs during tungsten CVD involves tungsten transport by the formation and disproportionation of volatile tungsten subfluorides. We present some recent measurements of the tungsten subfluoride formation rate using the microbalance technique.

Poppet valves and valve seats, for example, require resistance to surface damage from repetitive impacts. Grinding and finishing processes can leave microcracks or residual stresses in the surfaces of ceramics which can accelerate surface-initiated degradation processes. A ball-on-inclined plane, repetitive impact testing system has been developed to study the effects of finishing method on surface durability. Tests were performed by repeatedly striking ground alumina and silicon nitride flat specimens with a silicon nitride sphere and measuring the impact damage as a function of the number of strikes. One type of alumina and three types of silicon nitride ceramics were tested, A quantitative impact damage parameter (IDP), based on mechanical stylus profiling data, was developed for use in measuring small amounts of wear. When damage did not extend beyond the depth of valleys in the machined surfaces, the IDP exhibited an excellent linear correlation with the number of impacts of silicon nitride on both silicon nitride and alumina materials. When more extensive damage occurred, a method involving digitizing the area of the contact damage from photomicrographs provided a reasonable correlation with number of impacts. These two methods are compared. Scanning electron microscopy revealed features which can affect the accuracy of impact damage measurement. Implications of the technique are discussed.

In the pull test, pins that have been bonded to the coating under test are pulled with increasing force normal to the coating until the coating is pulled from the substrate. For many systems, large scatter in the data is often observed due to uncontrolled defects in the interface and the brittle nature of the pull test. In this study, the applicability of Weibull statistical analysis to the adhesion of Ag coatings to vacuum sputter-cleaned zirconia was examined. Data were obtained for smooth and rough substrates for various levels of adhesion. A good fit of the data to the Weibull distribution was observed. The Weibull modulus was found to depend on the roughness of the substrate but was insensitive to the adhesion strength. This seems to be the first reported application of Weibull statistical analysis to pull test data. C1 UNIV ILLINOIS,URBANA,IL 61801.

FIV infected cats shed significantly higher amounts of FCV through their saliva after FCV challenge than the non-FIV infected cats. However, there was no difference in the duration of FCV shedding. None of the cats exposed to FCV developed chronic FCV carriage. Both groups of cats mounted similar titers of neutralizing antibodies to FCV. Although FIV infected cats started out with significantly lower total lymphocyte and neutrophil numbers than the non-FIV infected cats, the transient lymphopenia and neutrophilia attributable to the FCV infection was of similar intensity in bath groups of animals. There was no evidence that the underlying FIV-related disease or viremia was influenced by acute FCV infection. Acute FCV infection did not significantly alter the CD4+/CD8+ T lymphocyte ratio in FIV infected compared to non-FIV infected cats. The ongoing humoral IgG response to FIV was not affected by the FCV infection. There was no significant change in the proportion of FIV infected peripheral blood mononuclear cells during 8 subsequent weeks after FCV challenge as determined by polymerase chain reaction.

The APN1 locus is located similar to 235 kb from the left telomere of chromosome XI, and shows weak (similar to 53 cM) genetic linkage to ural. The YUH1 locus is located similar to 140 kb from the right telomere of chromosome X, and genetically maps 3.6 cM distal to cdc11. In addition, we show by random-breakage mapping that TRP3 is located similar to 45 kb from the left telomere of chromosome XI, whereas FAS1 is similar to 110 kb from the same telomere. This supports a gene order on the left distal portion of chromosome XI that agrees with other physical reports but is inverted with respect to Edition 11 of the published genetic map. This report confirms that random-breakage mapping is a rapid and convenient method of locating cloned genes. C1 HARVARD UNIV,SCH PUBL HLTH,DEPT MOLEC & CELLULAR TOXICOL,BOSTON,MA 02115.

Emitted gamma-rays were detected with the EUROGAM array comprising 43 Compton-suppressed large volume Ge detectors. The level scheme of 192Hg has been extended up to an excitation energy of E = 10.4 MeV and spin I = 34 h. Two new structures, made of competing DELTAI = 1 and DELTAI = 2 transitions have been observed and their connexions with the low-lying levels established. Their lowest levels are located at 6.304 MeV and 6.879 MeV excitation energy. The experimental results are compared with mean-field HF + BCS calculations. It is proposed that the new structures originate from deformation-aligned quasi-proton excitations pi(i13/2*h9/2)K = 11 and pi(h9/2)K = 8(2), coupled to rotation-aligned quasi-neutron nu(i13/2)n and quasi-proton pi(h11/2)2 excitations.

This analysis focusses on the comparison between undoped and doped compounds. The proportionality between the orderparameter and the orthorhombic strain, predicted by the Landau theory, can be confirmed in La2-xSrCuO4+delta in a wide concentration and temperature range. We observe different values for the critical exponent beta for doped superconducting and undoped insulating crystals. The temperature dependent study of the soft modes on a metallic superconducting crystal reveals an extremely large temperature range where this mode is strongly anharmonic. The comparison with previously published data shows that the frequencies of the soft modes at low temperatures decrease with doping, i.e. with increasing charge carrier concentration.

There is evidence that electrochemical effects can cause short stress corrosion cracks to grow at rates which are either faster or slower than those of long cracks. Short cracks can grow at faster rates than long cracks for a salt film dissolution growth mechanism or from reduced oxygen inhibition of hydrolytic acidification. An increasing crack growth rate with increasing crack length could result from a process of increasing crack tip concentration of a critical anion, such as Cl-, with increasing crack length in a system where the crack velocity is dependent on the Cl- or some other anion concentration. An increasing potential drop between crack tip and mouth would result in an increased anion concentration at the crack tip and hence an increasing crack velocity. Stage I behavior of long cracks is another early development stage in the life of a stress corrosion crack which is poorly understood. This stage can be described by da/dt = AK(m) where da/dt is the crack velocity, A is a constant, K is the stress intensity and m ranges from 2 to 24 for a variety of materials and environments. Only the salt film dissolution model was found to describe this stage quantitatively; however, the model was only tested on one material and its general applicability is unknown.

The propensity for crack tip deformation is estimated on the basis of the calculated antiphase boundary (APD), complex stacking fault and superlattice intrinsic stacking fault energies and the anisotropic coupling effect on dislocation mobility, i.e. non-Schmid effects. It is shown that while the calculated Griffith energy of Ni3Si is larger than that of Ni3Al, dislocation emission from a crack tip is easier and dislocation mobility is higher in Ni3Al than in Ni3Si. When a crack is loaded in a mixed mode (K-I + K-III), emission of a super-Shockley partial from the crack trailing extended SISF is predicted and confirmed by in situ straining transmission electron microscopy observations of Ni3Al.

Since the non-critical string limit of the matrix model involves taking the parameters lambda and mu of the matrix model to a critical point, zero modes of the field might be important in this study. The constrained light-cone quantization (CLCQ) approach of Heinzl, Krusche and Werner is applied. It is found that there is coupling between the zero mode sector and the rest of the theory, hence CLCQ should be implemented.

Single crystals can be prepared through a transport reaction utilizing BaMoO4, MoO2, and Mo reagents in the presence of water vapor. Its properties are characterized via single-crystal and powder X-ray diffraction, magnetic susceptibility, and electrical resistivity measurements. Ba3Mo18O28 crystallizes in the centrosymmetric monoclinic space group P2(1)/a, with cell parameters a = 9.939(2) angstrom, b = 9.377(2) angstrom, c = 13.057(2) angstrom, beta = 100.92(1)degrees, V = 1194.7(3) angstrom3, Z = 2, and R = 0.0427 (R(w) = 0.0509) for 1284 reflections with I > 3sigma(I). The compound contains Mo18O42 clusters with strong metal-metal bonding. These clusters consist of four trans edge-shared molybdenum octahedra bridged on all edges by oxygen atoms. A prominent feature of these tetrameric units is the extreme short-long-short arrangement of apical-apical molybdenum bond distances. The tetrameric clusters are interconnected in a stair-step fashion via Mo-O bonding. The sharing of oxygen atoms between clusters can be represented by the connectivity formula [(Mo18Oi14Oi-i4/2Oi-a12/2)Oa-i12/2]6-. Pockets created by the interconnected clusters are filled with barium atoms. Mo-Mo bond order and Mo-O bond valence sums indicate 61.7(6) and 58(2) electrons available for metal-metal bonding (MCE), respectively. The bond valence sums are in excellent agreement with the 58 MCE expected on the basis of formal oxidation states. This compound was found to have a large chi(TIP) contribution to the magnetic susceptibility. Resistivity measurements on a sintered, pressed pellet showed that the material is a small band gap semiconductor, as expected from the long (>3.17 angstrom) intercluster Mo-Mo distances.

Boron neutron capture therapy (BNCT) is a binary treatment that allows selective tumor irradiation. This study evaluates the damage imparted to the normal brain during BNCT or x-irradiation. Methods and Materials: The brains of rats with implanted 9L gliosarcomas were examined 1 year after tumor-curative doses of either 250 kV X rays or BNCT. Histopathologic techniques included hematoxylin and eosin staining, horseradish peroxidase perfusion, and electron microscopy. Results: Longterm X ray survivors showed extensive cortical atrophy, loss of neurons, and widespread leakage of the blood-brain barrier (BBB), particularly around the tumor scar. In contrast, the brains and the BBB of longterm BNCT survivors appeared relatively normal under both light- and electron-microscopic examination. Intact blood vessels were observed running directly through the avascular, collagenous tumor scar. Conclusion: The selective therapeutic effect of BNCT is evident in comparison to x-irradiation. Both groups of animals showed no evidence of residual tumor at 1 year. However, with x-irradiation there is no therapeutic ratio and tumor eradication severely injures the remaining brain parenchyma. These observations indicate a substantial therapeutic gain for BNCT. C1 UNIV ROCHESTER,SCH MED,DEPT RADIAT ONCOL,ROCHESTER,NY 14642. UNIV ROCHESTER,SCH MED,DEPT NEUROBIOL & ANAT,ROCHESTER,NY 14642.

Methods and Materials: Pharmacokinetic and tissue distribution studies: MRA 27 cells (2 X 10(5)) were implanted intracerebrally, and 30 days later, 120 mg of B-10-L-BPA were injected intraperitoneally into nude rats. Therapy experiments: Thirty days following implantation, tumor bearing rats were irradiated at the Brookhaven Medical Research Reactor. Results: Pharmacokinetic experiments: Six hours following administration of BPA, tumor, blood, and normal brain boron-10 levels were 23.7, 9.4, and 8.4 mu g/g respectively. Therapy experiments: Median survival time of untreated rats was 44 days compared to 76 days and 93 days for those receiving physical doses of 2.73 Gy and 3.64 Gy, respectively. Rats that had received both B-10-BPA and physical doses of 1.82, 2.73, or 3.64 Gy had median survival times of 170, 182, and 262 days, respectively. Forty percent of rats that had received the highest tumor dose (10.1 Gy) survived for > 300 days and in a replicate experiment 21% of the rats were longterm survivors (> 220 days). Animals that received 12 Gy in a single dose or 18 Gy fractionated (2 Gy X 9) of gamma photons from a Cs-137 source had median survival times of 86 and 79 days, respectively, compared to 47 days for untreated animals. Histopathologic examination of the brains of longterm surviving rats, euthanized at 8 or 16 months following BNCT, showed no residual tumor, but dense accumulations of melanin laden macrophages and minimal gliosis were observed. Conclusion: Significant prolongations in median survival time were noted in nude rats with intracerebral human melanoma that had received BNCT thereby suggesting therapeutic efficacy. Large animal studies should be carried out to further assess BNCT of intracerebral melanoma before any human trials are contemplated. C1 OHIO STATE UNIV,DEPT VET CLIN SCI,COLUMBUS,OH 43210.

Methods and Materials: Large retriever-type dogs were used and the irradiations were performed by single dose, 5 X 10 dorsal portal. Fourteen dogs were irradiated with the epithermal neutron beam alone and 35 dogs were irradiated following intravenous administration of borocaptate sodium. Results: Total body irradiation effect could be seen from the decreased leukocytes and platelets following irradiation. Most values returned to normal within 40 days postirradiation. Severe dermal necrosis occurred in animals given 15 Gy epithermal neutrons alone and in animals irradiated to a total peak physical dose greater than 64 Gy in animals following borocaptate sodium infusion. Lethal brain necrosis was seen in animals receiving between 27 and 39 Gy. Lethal brain necrosis occurred at 22-36 weeks postirradiation. A total peak physical dose of approximately 27 Gy and blood-boron concentrations of 25-50 ppm resulted in abnormal magnetic resonance imaging results in 6 months postexamination. Seven of eight of these animals remained normal and the lesions were not detected at the 12-month postirradiation examination. Conclusion: The bimodal therapy presents a complex challenge in attempting to achieve dose response assays. The resultant total radiation dose is a composite of low and high LET components. The short track length of the boron fission fragments and the geometric effect of the vessels causes much of the intravascular dose to miss the presumed critical target of the endothelial cells. The results indicate a large dose-sparing effect from the boron capture reactions within the blood. C1 KANSAS STATE UNIV AGR & APPL SCI,DEPT RADIOL,MANHATTAN,KS 66502.

In this study, the pathologic effects of BNCT on the central nervous system (CNS) have been investigated using a rat spinal cord model. Methods and Materials: The neutron capture agent used was B-10 enriched sodium mercaptoundecahydro-closo-dodecaborate (BSH), at a dosage of 100 mg/kg body weight. Rats were irradiated on the thermal beam at the Brookhaven Medical Research Reactor. The large spine of vertebra T-2 was used as the lower marker of the irradiation field. Rats were irradiated with thermal neutrons alone to a maximum physical absorbed dose of 11.4 Gy, or with thermal neutrons in combination with BSH, to maximum absorbed physical doses of 5.7 Gy to the CNS parenchyma and 33.7 Gy to the blood in the vasculature of the spinal cord. An additional group of rats was irradiated with 250 kVp X rays to a single dose of 35 Gy. Spinal cord pathology was examined between 5 and 12 months after irradiation. Results: The physical dose of radiation delivered to the CNS parenchyma, using thermal neutron irradiation in the presence of BSH, was a factor of two to three lower than that delivered to the vascular endothelium, and could not account for the level of damage observed in the parenchyma. Conclusion: The histopathological observations of the present study support the hypothesis that the blood vessels, and the endothelial cells in particular, are the critical target population responsible for the lesions seen in the spinal cord after BNCT type irradiation and by inference, after more conventional irradiation modalities such as photons or fast neutrons.

Such calculations are an essential component of in vivo BNCT research and will ultimately also be required for human BNCT treatment planning. Calculations of macroscopic absorbed dose distributions for BNCT are more complex than for photon therapy. There are several different dose components, each of which has its own characteristic spatial distribution, linear energy transfer, and relative biological effectiveness (RBE). Three-dimensional (3-D) energy-dependent radiation transport models with a detailed treatment of particle scattering are required. Geometric descriptions for such models are typically constructed directly from medical image data and both the Monte Carlo stochastic simulation method and the discrete-ordinates deterministic approach have been successfully used to perform the necessary radiation transport calculations. Microdosimetric effects can profoundly influence the therapeutic benefit that may be attainable in BNCT. These effects must be carefully taken into account in the interpretation of experimental data, especially when correlating observed in vivo radiobiological response with absorbed radiation dose. Calculations of microdosimetric parameters for BNCT are typically performed using the Monte Carlo method to generate single-event energy deposition frequency distributions for critical targets in various cell types of interest. This information is useful in the development of apparent RBE factors, or ''compound factors'' for the various dose components in BNCT.

Methods and Materials: The beam was reevaluated using Monte Carlo calculations and flux and dose measurements in air and in an ellipsoidal head phantom at the patient irradiation port. Changes in its geometry and materials were considered, including rearranging the fuel elements in the reactor core and redesigning the moderator and the patient irradiation port. Results: Calculations of the new fluxes and doses at the patient irradiation port showed that the epithermal neutron flux can be increased by 100%, while the fast neutron dose per epithermal neutron can be reduced by 38%. In 1992, some of the proposed changes were made. In June 1992, measurements were made after one additional fuel element was added to replace a graphite spacer block on the epithermal beam side of the reactor core. The results show that the epithermal neutron flux increased by 18%, as predicted by the Monte Carlo calculations. In October 1992, the fuel elements in the reactor core were rearranged by placing four new fuel elements in the first row facing the epithermal port; the intensity of the epithermal neutron beam increased by 50% and the fast neutron and gamma doses per epithermal neutron may have decreased slightly. Conclusion: The epithermal neutron beam at the Brookhaven Medical Research Reactor has gained a 50% increase in the epithermal neutron flux and the fast neutron and gamma doses per epithermal neutron are reduced slightly after the rearrangement of the fuel elements in the core.

Methods and Materials: At present, the tumor-bearing rat is positioned in a rat holder that functions as a whole-body radiation shield. A 2.54 cm-thick collimator with a centered conical aperture, 6 cm diameter tapering to 2 cm diameter, is used to restrict the size of the thermal neutron field. Using the present holder and collimator as a baseline design, Monte Carlo calculations and mixed-field dosimetry were used to assess new designs. Results: The computations indicate that a 0.5 cm-thick plate, made of (Li2CO3)-Li-6 dispersed in polyethylene (Li-poly), instead of the existing rat holder, will reduce the whole-body radiation dose. Other computations show that a 10.16 cm-thick (4 inches) Li-poly collimator, having a centered conical aperture of 12 cm diameter tapering to 2 cm diameter, would further reduce the whole-body dose. Conclusion: The proposed irradiation apparatus of tumors in the rat brain, although requiring a 2.3-fold longer irradiation time, would reduce the average whole-body dose to less than half of that from the existing irradiation assembly.

This bimodal treatment modality selectively concentrates a boron compound in malignant cells, and then ''activates'' this compound with slow neutrons resulting in a highly lethal event within the cancer cell. This article will review this treatment modality from a radiation oncology, biology, and physics perspective. The remainder of the articles in this special issue of the Journal will provide a survey of the current ''state-of-the-art'' in this rapidly expanding field, including information with regard to boron compounds and their localization.

Additionally, homozygosity for A(y) results in preimplantation lethality, which terminates development by the blastocyst stage. The A(y) mutation is the result of a 170-kb deletion that removes all but the promoter and noncoding first exon of another gene called Raly, which lies in the same transcriptional orientation as agouti and maps 280 kb proximal to the 3' end of the agouti gene. We present a model for the structure of the A(y) allele that can explain the dominant pleiotropic effects associated with this mutation, as well as the recessive lethality, which is unrelated to the agouti gene.

The binding was detected by a gel mobility-shift assay. This approach was tested by using as a model the most commonly occurring mutations within the cystic fibrosis (CFTR) gene. Genomic DNA samples were amplified with 5'-end-labeled primers that bracket the site of the DELTAF508 3-bp deletion in exon 10 of the CFTR gene. The renatured PCR products from homozygotes produced homoduplexes; the PCR products from heterozygotes produced heteroduplexes and homoduplexes (1:1). MutS protein bound more strongly to heteroduplexes that correspond to heterozygous carriers of DELTAF508 and contain a CTT or a GAA loop in one of the strands than to homoduplexes corresponding to homozygotes. The ability of MutS protein to detect heteroduplexes, in PCR-amplified DNA extended to fragments almost-equal-to 500 bp long. The method was also able to detect carriers of the point mutations in exon 11 of the CFTR gene by a preferential binding of MutS to single-base mismatches in PCR-amplified DNA.

This region shares homology with a segment of human chromosome 15 that is implicated in Angelman syndrome, an inherited neurobehavioral disorder. By mapping Gabrg3 on a panel of p-locus deletions, we have determined that the order of genes within this cluster is centromere-p(D15S12h)-Gabrg3-Gabra5-Gabrb-3-telomere. Like Gabrb3, neither the Gabra5 nor Gabrg3 gene is functionally imprinted in adult mouse brain. Mice deleted for all three subunits die at birth with a cleft palate, although there are rare survivors (almost-equal-to 5%) that do not have a cleft palate but do exhibit a neurological abnormality characterized by tremor, jerky gait, and runtiness. We have previously suggested that deficiency of the beta3 subunit may be responsible for the clefting defect. Most notably, however, in this report we describe mice carrying two overlapping, complementing p deletions that fail to express the gamma3 transcript, as well as mice from another line that express neither the gamma3 nor alpha5 transcripts. Surprisingly, mice from both of these lines are phenotypically normal and do not exhibit any of the neurological symptoms characteristic of the rare survivors that are deleted for all three (gamma3, alpha5, and beta3) subunits. These mice therefore provide a whole-organism type A gamma-aminobutyric-acid receptor background that is devoid of any receptor subtypes that normally contain the gamma3 and/or alpha5 subunits. The absence of an overt neurological phenotype in mice lacking the gamma3 and/or alpha5 subunits also suggests that mutations in these genes are unlikely to provide useful animal models for Angelman syndrome in humans.

The facets are composed of three vicinal surfaces tilted about 2-degrees toward [211BAR], [121BAR], and [112BAR] directions, respectively. The diffusion length at the growth condition is estimated from the surface morphologies and found to be at least hundreds of nanometers. It is comparable to the diffusion length on the (100) surface grown under the same conditions. Therefore, the facet formation on GaAs (111BAR) film is unlikely caused by slower surface mobility.

We calculate these intensities as function of ordering parameter eta, and show that the transition intensities depend strongly on the light polarization e and the degree of long-range order eta in the sample. Furthermore, for sufficiently ordered single-subvariant sample, 100% spin polarization of emitted photoelectrons is predicted.

Analysis of positron annihilation spectroscopy data indicates voidlike structures in a defective layer extending to almost-equal-to 14 nm from the surface at a concentration of 1.9-0.5 X 10(20) cm-3. The Doppler broadening parameter for the annihilation gamma rays is strongly correlated to the hydrogen coverage of the void surfaces, voids remain in the Si to at least 800-degrees-C while the hydrogen is desorbed from their surfaces between 600 and 800-degrees-C.

These cross sections have been integrated by employing a nonlinear phase shift fitting procedure to generate a list of integral elastic and momentum transfer cross sections for the same energy range. The angular distributions have been found to agree reasonably well with a continuum multiple scattering calculation using only local potentials and also with a multichannel Schwinger variational calculation. Limited experiments on vibrationally inelastic scattering reveal the existence of a shape resonance with a peak at approximately 2 eV that is characteristic of trapping by a valence orbital with Si-H antibonding character analogous to that encountered in e-monosilane scattering.

This enhanced capability will open up new possibilities for research on the structure of and phenomena occurring in proton-rich nuclei. Among the opportunities will be the creation of heavier N almost-equal-to Z nuclei approaching Sn-100, and the study of exotic nuclear shapes, extensions of studies of the p-n interaction and super-allowed beta decay, and examination of nuclear structure near the proton drip line. In addition to new nuclear and atomic physics research opportunities, the beams from the Holifield RIB facility are expected to provide new capabilities for measurements important to nuclear astrophysics. To carry out this experimental program, various upgrades are planned to the existing experimental apparatus, and a new, third-generation, recoil-mass separator is being constructed.

at the Fermilab Tevatron. Assuming that H+ --> taunu(tau) is the dominant H+ decay mode, we exclude regions of the (m(H) +,m(t)) plane for values of the branching ratio B(H+ --> taunu(tau)) = 0.5, 0.75, and 1.0. We interpret the results in terms of the parameter tanbeta in the two-Higgs-doublet model. C1 BRANDEIS UNIV,WALTHAM,MA 02254. UNIV CALIF LOS ANGELES,LOS ANGELES,CA 90024.

The results are consistent with scattering from a single nucleon as the dominant process. The nuclear transparency is obtained and compared with theoretical calculations that incorporate color transparency effects. No significant rise of the transparency with Q2 is observed.

The degeneracy of this state is broken by crystalline effects, and realistic calculations for UPt3 find a pair state with GAMMA6- (E2u) symmetry, consistent with current experimental constraints.

A semi-direct algorithm for eliminating this fifth-order storage is described in which small batches of MO integral derivatives are made at a time, their contributions to the MP2 second derivatives are evaluated, and then they are discarded. No extra computation is required. We locate and characterize a transition structure of the water hexamer cluster which exhibits a bifurcated hydrogen bond structure, at the MP2/6-31 + G* level of theory.

The 'DEAD/H' family of putative RNA helicases may help regulate these processes by utilizing intrinsic RNA-dependent ATPase activity to catalyze conformational changes in RNA secondary structure. To investigate the repertoire of DEAD/H box proteins expressed in mammals, we used PCR techniques to clone from mouse erythroleukemia (MEL) cells three new DEAD box cDNAs with high similarity to known yeast (Saccharomyces cerevisiae) genes. mDEAD2 and mDEAD3 (mouse DEAD box proteins) are >95% identical to mouse PL10 but exhibit differential tissue-specific expression patterns, mDEAD2 and mDEAD3 are also approx. 70% identical (at the aa level) to yeast DED1 and DBP1 proteins. Members of this DEAD box subclass contain C-terminal domains with high content of Arg, Ser. Gly and Phe, reminiscent of the RS domain in several Drosophila and mammalian splicing factors. mDEAD5 belongs to a second class related to translation initiation factors from yeast (TIF1/TIF2) and mammals (eIF-4A); this class contains a novel conserved peptide motif not found in other DEAD box proteins. Northern blotting shows that mDEAD5 is differentially expressed in testis vs. somatic tissues. Thus, mouse erythroid cells produce two highly conserved families of putative RNA helicases likely to play important roles in RNA metabolism and gene expression.

It has been implicated in the repression of transcription(2,5), and phosphorylation of H1 may be involved in cell-cycle-dependent chromatin condensation and decondensation(6). A long-standing issue concerns the location of H1 in the chromatin filament(7). The original solenoidal model(8) proposes that H1 is inside the 30-nm filament, but other models, also helical, suggest a variable(9) or more accessible(10) location for H1. Investigations to determine the location of the linker histone based on its accessibility to antibodies(11-15) or immobilized proteases(16) under various ionic conditions have yielded conflicting results. Here we use neutron scattering in a direct structural determination to show that H1 is located in the interior of the filament. C1 BROOKHAVEN NATL LAB,DEPT BIOL,UPTON,NY 11973.

The model allows for the possibility of a small degree of (dynamically determined) tunneling of quarks between different nucleons in the nucleus. We find that the systematics of the A = 3/A = 4 systems are correctly reproduced by the model - in particular, nuclear scale binding arises naturally from the cancellation between hadronic scale effects - strengthening the case for the presence of such tunneling (nucleon distortion) in the nucleus.

Although the probability of geminate recombination (P(r)) diminishes for the unlabeled pair, from 0.549 to 0.436 and for the labeled pair from 0.585 to 0.504 at zero magnetic field with decreasing micelle size (C-12 to C-8), the efficiency of isotope separation (alpha) is found to increase at zero magnetic field from 1.144 to 1.236 with decreasing micelle size. Theoretical considerations of these experimental results show that the rate of geminate reaction of the unlabeled radical pairs in small micelles is sensitive to the electron spin exchange interaction; intersystem crossing is influenced by fast forced reencounters. These effects are not as important for the labeled radical pairs (which possess a strong C-13 hyperfine interaction). In addition, paramagnetic relaxation due to anisotropic hyperfine and electron-electron dipole interactions is shown to be important in the quantitative description of the micelle size dependence of the reaction ability of the labeled radical pairs.

Other potential initiator, [1,4-phenylenebis(eta3-1-allyl)nickel trifluoroacetate)]n, II, and [1,4-cyclohexanediylbis((eta3-1-allyl)-nickel trifluoroacetate)]n, III, were found to be completely ineffective due to intermolecular carboxylate bridges which gave the complexes polymeric structures. The intramolecular bridges in IV and its molecularity were confirmed by X-ray crystallography.

Design criteria and specific examples are presented for high energy, orbit transparent spin rotators ranging from small angle rotators to be used for the excitation of spin resonances to large angle rotators to be used as Siberian Snakes.

The glasses are cerium-doped lithium-aluminosilicates. Scintillation light output measurements were made as a function of lithium and alumina concentration and of annealing history. In this system, the cerium outer electron cloud serves as a sensitive probe of the local glass structure. From these measurements, a sensitivity matrix relating the light output to the structure is developed and presented. A conceptual model for the behavior of the light output is also presented.

Hydrogen is generally believed to be necessary for the diamond thin-film growth process. However, hydrogen in varying amounts is inevitably incorporated in the growing diamond lattice, leading to structural defects. We report here the successful growth of diamond films using fullerene precursors in an argon microwave plasma, a unique development achieved without the addition of hydrogen or oxygen. We speculate that collisional fragmentation of C60 to give C2 could be responsible for the high growth rate of the very-fine-grained diamond films. C1 ARGONNE NATL LAB,DIV CHEM,ARGONNE,IL 60439.

Nitrogen was introduced into internal reflection plates of polycrystalline ZnSe by ion implantation. Isotopic substitution confirmed assignment of the absorption to N, and the band frequency is consistent with N on Se sites. Coimplantation with deuterium decreased the N band intensity and introduced a band for Zn-D. These deuterium effects which increase upon annealing between 200 and 300-degrees-C are ascribed to a breaking of Zn-N bonds to form Zn-D bonds and a relaxation of N toward threefold coordination.

The implantation was performed at both room temperature (RT) and liquid nitrogen temperature (LNT). After annealing at 850-degrees-C for 5 s, both sets of samples exhibited n-type conductivity. The n-type activation efficiency in the RT implanted sample was about a factor of 2 higher than that in the LNT sample (15% and 8%, respectively). Extended x-ray absorption fine structure spectroscopy (EXAFS) shows direct evidence of the amphoteric substitutionality of the Ge atoms in InP for both samples. The ratios of Ge on In sites to Ge on P sites, derived from the EXAFS results, are consistent with the electrical behavior of the samples. The EXAFS results also reveal that the Ge-In and Ge-P bond lengths in the RT sample are very similar to their theoretical values, but are very different from the original In-P bond length. A relaxation in the Ge-In bond is observed in the LNT sample, resulting in a Ge-In bond length very similar to the original In-P bond length. C1 UNIV CALIF BERKELEY,DIV ENGN,BERKELEY,CA 94720.

Using detailed plane-wave ab initio pseudopotential local density functional (LDA) calculations, we find that the electronic properties of small tubes are significantly altered from those obtained in previous tight-binding calculations. Strongly modified low-lying conduction band states are introduced into the band gap of insulating tubes because of strong sigma*-pi* hybridization. As a result, the LDA gaps of some tubes are lowered by more than 50%, and a tube previously predicted to be semiconducting is shown to be metallic.

The ground states are determined for the complete range of parameters by using a combination of numerical and analytical techniques.

In fact, they can balance the capture rates during the conditions which are prevalent after core silicon burning, resulting in a new Urca process. The strength of the beta-decay rates is a result of thermal population of the Gamow-Teller back resonance in the parent nucleus and the behavior of beta-decay and electron capture Q-values for ensembles of nuclei in nuclear statistical equilibrium. All beta-decay rate tabulations prior to Fuller, Fowler, and Newman neglected the contribution of back resonances and thus drastically underestimated the overall rate. We use a simple analytic model to explain this balancing. The full rates are coupled to a nuclear statistical equilibrium code to demonstrate the strength of the decays. One zone models are used to examine, in a self-consistent fashion, how these rates could affect the presupernova evolution of the iron core and hence the core collapse problem.

In the optical and UV, V347 Pup is a strong emission line source with a continuum spectrum which is remarkably red for a high-M cataclysmic variable. Consistent with its high inclination, we interpret the continuum spectrum as the superposition of the spectrum of the cool (T(eff) almost-equal-to 7000 K) outer edge and the hot (T(eff) almost-equal-to 100,000 K) inner regions of a self-eclipsed accretion disk. For the assumed parameters, the model matches the level and shape of the observed spectrum for an inclination of almost-equal-to 88-degrees and a distance of almost-equal-to 300 pc. The prominent hump in the optical and UV light curves just before eclipse manifests the presence of the hot spot where the accretion stream strikes the edge of the disk. The wavelength dependence of the amplitude of the hump is best modeled by a spot having an effective temperature of almost-equal-to 25,000 K and an area of almost-equal-to 3 x 10(18) cm2 if the spot radiates like a blackbody, or an effective temperature of almost-equal-to 14,000 K and an area of almost-equal-to 3 x 10(19) cm2 if it radiates with a stellar spectrum. In either case, the hot spot produces only one-tenth of the predicted luminosity for the assumed mass-transfer rate of 10(-8) M, yr-1. Either the hot spot is ''buried'' in the edge of the accretion disk, or a significant fraction of its luminosity is radiated away in lines. The difference in azimuth between the peak of the hump and the dynamically expected location of the hot spot suggests that the spot's emitting surface is rotated forward by almost-equal-to 36-degrees relative to the edge of the disk. Phase-resolved optical spectroscopy demonstrates that the optical continuum and emission line regions in V347 Pup have the same radial extent, that the bulk of the Hbeta emission line arises in the accretion disk but that it may also have a modest vertical extent, that the He II lambda4686 emission volume is both more sharply defined in the radial coordinate and less extended in the vertical direction, and that both the Hbeta and He II lambda4686 lines become narrower in eclipse, consistent with the eclipse of the inner, higher velocity, disk regions. In contrast, phase-resolved IUE spectroscopy demonstrates that the UV emission lines are only partially occulted in eclipse, indicating that they are formed in a region with dimensions comparable to the size of the secondary. Furthermore, the UV emission lines narrow only slightly in eclipse and have radial velocities which are delayed in phase relative to the optical emission lines by approximately 0.1 orbital cycles. The UV lines are modeled (poorly) by resonant scattering of accretion disk photons in a radially expanding wind emanating from the center of the disk. The required long acceleration scale and high wind mass-loss rate, combined with the prediction that the line widths should increase rather than decrease in eclipse, suggest that more complicated wind geometries may be necessary to explain the observed properties of the UV emission lines, including a possible rotational component near the disk plane and an additional emission component from the location of the hot spot. Finally, ROSAT survey observations indicate that V347 Pup is a weak and moderately soft X-ray source. Because of its high inclination, we argue that the X-rays do not come directly from the boundary layer but instead come from an extended emission volume. Possible sources of this emission include soft X-rays produced by shocks in the high-velocity wind and soft boundary layer X-rays which are scattered by the wind into the line of sight.

We examine a poor (2 keV) cluster formed in a biased, cold dark matter cosmology and employ simple, but plausible, threshold criteria to convert gas into stars. At z = 2, the forming cluster appears as a linear chain of very blue (g - r congruent-to 0) galaxies, with 15 objects brighter than r = 25 within a 1 square arcmin field of view. After 2 Gyr of evolution, the cluster viewed at z = 1 displays both freshly infalling blue galaxies and red galaxies robbed of recent accretion by interaction with the hot intracluster medium. The range in G - R colors is - 3 mag at z = 1, with the reddest objects lying at sites of highest galaxy density. We suggest that red, high-redshift galaxies lie in the cores of forming clusters and that their existence indicates the presence of a hot intracluster medium at redshifts z congruent-to 2. The simulated cluster viewed at z = 2 has several characteristics similar to the collection of faint, blue objects identified by Dressler et al. in a deep Hubble Space Telescope observation. The similarities provide some support for the interpretation of this collection as a high-redshift cluster of galaxies. C1 UNIV CALIF BERKELEY,DEPT ASTRON,BERKELEY,CA 94720.

Agreement between the calculated and measured spectra is very encouraging.

This work studies how the stability of single foam films, as gauged by the magnitude of their disjoining pressures, influences the flow resistance of foam in porous media. Steady state pressure gradients of flowing foam in 2.3 mum2 permeability glass beadpacks and disjoining pressure isotherms of single foam films are measured for 10(-3) M and 0.017 M sodium dodecyl sulfate (SDS) solutions with and without NaCl. The constant-rate flow experiments show that the addition of salt to 10(-3) M SDS increases the pressure gradient in the beadpacks from 0.1 to 4 MPa m-1 at 0.50 M NaCl. Surfactant solutions of 0.017 M SDS content exhibit pressure gradients of 22 MPa m-1, quite independent of salt concentration. Likewise addition of salt to the 10(-3) M SDS solutions dramatically influences the disjoining pressure isotherms by raising the rupture pressure from 0.5 to above 15 kPa at 0.50 M NaCl. The 0.017 M SDS solutions display rupture pressures above 30 kPa, independent of salt concentration. We conclude that high repulsive disjoining pressures in single foam films lead to strong foam in porous media with large flow resistance. Further, we find that the limiting capillary pressure for rapid foam coalescence in porous media is close to the rupture pressure of foam lamellae as obtained from measured disjoining pressure isotherms.

The high resolution and accurate mass measurements possible with this instrumentation are demonstrated by application to the heterogeneous glycoprotein, Ribonuclease B (RNase B). The high resolution routinely attainable allows unambiguous charge state assignments, and thus, precise mass determination for all ions observed and demonstrates the utility of ESI-FTICR for the analysis of complex biological mixtures. In addition, results are presented for the dissociation of RNase B in both the electrospray source and in the ICR cell. The results show that phosphate adducts to RNase B molecular ions are most readily dissociated in the heated capillary inlet, less effectively by collisional activation in the 1-10 Torr capillary-skimmer region, and with significantly reduced efficiency by collisional activation in the ICR cell, where other dissociation processes dominate. This trend is correlated with the extent of molecular ion solvation expected in the three regions, and suggests that phosphate adduct removal is most effective for solvated molecular ions.

Isotope beat fequencies can readily and accurately be predicted from the difference in cyclotron frequencies of neighbouring isotope peaks. The nature of these signals has important implications for high resolution mass analysis, particularly in instances where rapid spectral acquisition is desirable such as with on-line analysis of chromatographic/electrophoretic effluents. Due to the pulsed nature of the frequency information in these transients, resolution improvements are effectively realized in a stepwise nature. As will be demonstrated, the application of apodization functions can have deleterious effects on signal-to-noise and resolution when beats are present only near the beginning and end of the transient. Additionally, in instances where the length of FTICR data acquisition is critical (such as in conjunction with on-line separations or in the analysis of very high molecular weight species), it is crucial to choose data acquisition parameters based on the predicted behavior of the time domain signal for the efficient and accurate acquisition of mass spectra.

The effects of electric field on electron transfer were separated from the effects of field-enhanced charge separation and surface recombination through a rigorous numerical solution of the coupled continuity and Poisson equations using a Cray supercomputer. A very strong dependence of the electron-transfer velocity (S(et)) on V(BO) was found, S(et) reached a saturation value of 5 X 10(7) cm/s when the initial value of V(BO) in the dark was greater-than-or-equal-to 0.5 eV. When the initial value of V(BO) was set near zero, S(et) was 9 X 10(3) cm/s. Hot electron injection processes appear to play a role in this behavior. C1 CORNELL UNIV,CTR MAT SCI,ITHACA,NY 14853.

These three different techniques have only a few disagreements among them, the case of ethylene being the most serious. For the overwhelming number of studies, all measurements lead to bond energies within each other's error bars.

We derive scaling relations for the partition function and physical observables in this conformal phase, and suggest quantitative tests of these relations in numerical simulations of simplicial four geometries with S4 topology. In particular, we predict the form of the critical curve in the coupling constant plane, and determine the scaling of the Newtonian coupling with volume which permits a sensible continuum limit. The existing numerical results already provide some evidence of this infrared fixed point and new conformal invariant phase of quantum gravity.

It is concluded that a significant nu(e)-nu(s) mixing may hinder the ability of the supernova to explode. It may also cool the proto-neutron star too quickly with respect to the observed cooling time of several seconds. The constraints on the nu(e)-nu(s) mixing parameters based on the above arguments are calculated. C1 FERMILAB NATL ACCELERATOR LAB,NASA FERMILAB ASTROPHYS CTR,BATAVIA,IL 60510.

The carbodiimide-binding procedure, which allows the formation of an amide bond between the aromatic carboxylic group of Indo-1 and an amino group of the gel has been selected for this study. In this work, agarose gel, which has an amino terminal group with a six-atom hydrophilic spacer arm, has been chosen for hosting Indo-1. A phase-transfer catalyst was used to allow efficient diffusion of metalions into the GBI probe. The results indicate that the GBI probe is an efficient and practical system that has the required sensitivity to detect Ca2+ ions in biological fluids for routine monitoring.

Species of cytochrome ba(3) investigated include its resting, as-isolated, fully oxidized state, the fully reduced, unliganded enzyme, the one-electron-reduced cyano complex,the three-electron-reduced cyano complex, and the fully reduced cyano complex. Results are compared to those obtained from similar adducts of bovine cytochrome aa(3), in particular, the fully reduced cyano complex. Our objective was to identify structural similarities and differences at the ligand-binding binuclear site of the two enzymes. We observed that the inner core skeletal vibrations of cytochrome a, are the same for similar adducts of the bacterial ba(3) and mammalian aa(3), indicating similar spin and iron-porphyrin coordination properties resulting in comparable porphyrin core geometries. On the other hand, many of the vibrational frequencies associated with the formyl and vinyl peripheral substituents, and the outer pyrrole carbon atoms differ between the bovine and bacterial enzymes. Use of Fe-57 labeled ba(3) allows identification of two separate vFe-N(His) frequencies displayed by the fully reduced, unliganded cytochrome. These frequencies, occurring at 193 and 209 cm(-1), are ascribed to distinct protein conformers, which are best evidenced by the Fe-N(His) vibrations. This result is again in contrast to the bovine enzyme which has been shown by others to display a single Fe-N(His) stretching frequency at 214 cm(-1). The low-frequency Fe-a3(2+)-CN- vibrations of the three-electron and fully reduced cyano complexes of cytochrome ba(3) are identified by using N-15 and C-13 isotopomers of CN-. These spectral signatures are identical to those reported earlier for the one-electron-reduced cyanide adduct (cytochrome a(3) reduced), showing that the Fe-a3(2+)-CN- vibrational frequencies are independent of the redox states of the other three metal centers. Similarly, the Cu-B(2+) EPR signatures appear similar in both the one-electron- and three-electron-reduced cyanide adducts. On the other hand, the electronic absorption spectra of ferrous a(3)-CN- show systematic red-shifts of the alpha band as each of the other metal centers is reduced, and other, more subtle, differences in the electronic absorptions of the three-electron-reduced and four-electron-reduced cyanide adducts are revealed in the difference spectra. The relevance of these findings toward explaining the different cyanide binding and redox chemistry described herein and toward establishing the extent of structural analogy between the oxygen binding sites of the two proteins is discussed.

To understand the kinetics of the biological destruction of CCl4 by these microbes, a set of experiments, the conditions of which were chosen according to a fractional factorial experimental design, were completed. This article reports on the experimental design along with the results for CCl4, biomass, acetate, nitrate, and nitrite concentrations. These data indicate that growth is inhibited by high nitrite concentrations, whereas CCl4 degradation is slowed by the presence of nitrate and/or nitrite. (C) 1994 John Wiley and Sons, Inc.

These STSs included 69 that had not been related to transcribed sequences and 5 that had detected two known genes and three previously isolated cDNA clones. Of the 69 STSs analyzed in RT-PCR, 25 allowed amplification of specific cDNA fragments. The sizes of amplified cDNA fragments match those amplified from either human genomic DNA or somatic hybrid cells containing human chromosome 21. Of the 11 cDNA analyzed in Northern blot hybridizations, 6 hybridized to specific RNA species. The rapid screening for cDNA using previously mapped STSs has provided insight into the distribution of expressed sequences in this region of chromosome 21. Northern blot analysis of the amplified cDNA fragments has revealed interesting candidate genes in two disease loci. The marker D21S267 was previously mapped in the Down syndrome region of chromosome 21, and the marker D21S113 is closely linked to progressive myoclonus epilepsy. The cDNA fragments amplified using the primer sequences derived from D21S267 and D21S113 hybridized to 7- and 6.5-kb transcripts, respectively, which seem to express predominantly in brain.

The theory attempts to be as ab initio and complete as necessary for describing a He plasma. The basic theoretical description incudes the time-dependent, electric-field-consistent Boltzmann equation for the electrons, inertial fluid equations for the heavy particles, and a multilevel model of the He excitations. The novel numerical algorithms are rapidly convergent. The experimental and theoretical absolute number densities are generally within a factor of 2 for both the electron plasma density and the metastable densities. In addition the spatial variation of the metastable populations (singlet and triplet) between the electrodes is well reproduced.

For the GaAs/Al0.4Ga0.6As samples that are first exposed to atmosphere, the experiment is performed in an integrated processing system where etching and regrowth chambers are linked together by ultrahigh vacuum transfer modules. The etching process includes electron cyclotron resonance (ECR) hydrogen plasma cleaning of GaAs native oxides, ECR SiCl4 plasma anisotropic deep etching into Al0.4Ga0.6As, and an optional, brief Cl2 chemical etching. Regrowth is carried out using solid-source molecular beam epitaxy (MBE). Despite the in situ processing, significant amounts of C, Si, and O impurities at the 10, 5, and 50 X 10(12) cm-2 levels exist at the interfaces. However, the impurity level is one order of magnitude smaller than that in air-exposed, ECR plasma etched and MBE regrown Al0.4Ga0.6As/GaAs of the set 2 samples. As revealed using TEM, isolated small particles (presumably correlated to aluminium oxides) exist at the regrown/processed interface of the set 1 samples, but no other defects such as dislocation are seen. Impurities and defects are mainly caused by the high reactivity of AlGaAs during ECR plasma etching. C1 SANDIA NATL LABS,ALBUQUERQUE,NM 87185.

Signal-intensity dependence on molecular wave functions, lifetimes, and laser beam polarizations is explicitly included in these equations. The emphasis of the presentation is on both physically intuitive interpretation and a practical, ''cookbook'' approach to spectral simulation. We present experimental verification of our calculations drawn from the spectrum of dilute Nd in N-2 at low pressures. Both degenerate two-level and three-level (crossover) resonances were observed. The experimental spectral intensities are accurately reproduced by the expressions presented here. We point out some of the Subtleties of DFWM spectra that could be used as aids to interpretation, especially the use of laser polarization as a probe for spectral line assignments.

Rydberg states are quenched in the solid, and the exchange splitting of the Is ionization threshold (1.1 eV) can be observed. Below the ionization threshold, core electrons can be excited into unoccupied antibonding pi* and o* orbitals. We conclude from the relative intensities and from the polarization dependence, that the exchange splitting of the o* final-state is small (<1 eV). This is confirmed by LDA calculations of core-excited states. The calculated dr potential surfaces are repulsive, which explains the large width of this absorption peak. Because of ultrafast dissociation (similar to 5 fs), core hole decay is likely to occur at large interatomic distances. Anger spectra at the o* absorption of O-2 do indeed show peaks that would be expected for free core-excited oxygen atoms. C1 BROOKHAVEN NATL LAB,DEPT PHYS,UPTON,NY 11973.

Stimulated emission pumping (SEP) is used to obtain rovibrational term energies for levels with up to 14 quanta of excitation in the large-amplitude vibration. We analyze the SEP data, as well as other available experimental data, using a semirigid bender model that allows for complete internal rotation within a triatomic molecule. From the least-squares fitting of this model to the data, we determine the potential energy along the minimum energy path of the large-amplitude vibration, the harmonic energies of the small-amplitude coordinate. The fitting is aided by results obtained from ab initio calculations we perform on the triangular and linear configurations of the molecule. The current data set is consistent with a large-amplitude potential energy function in which the energy difference between the triangular and linear configurations is 1883 cm(-1). The statistical error on this energy difference is 22 cm(-1), but we estimate the physical uncertainty to be about 200 cm(-1). This result is in excellent agreement with the energy difference of 1819 cm(-1) we obtain in our best ab initio calculations. The semirigid bender fitting and our best ab initio calculations are also both consistent with a potential energy function having no local minimum at linearity.

The HF molecule, initially in its ground state, is modeled as a rotating oscillator interacting with a classical laser field via electric dipole interaction. Realistic potential and dipole functions are used. Optimal overlaps of the five laser pulses, as well as the optimal carrier frequencies of the laser pulses, are found which maximize the HF dissociation yield. A maximal yield of 45% in a single combined pulse is achieved using the best available potential and dipole moment functions. The optimal infrared multiphoton dissociation pathway for the HF molecule includes a series of the Delta v=1 vibrational-rotational transitions followed by a series of Delta v greater than or equal to 2 vibrational-rotational transitions. The latter is necessary as a consequence of the vanishing Delta v=1 transition moment around v=12. In the Delta v=1 regime, both P and R branch transitions are found to be important. The angular distribution of the dissociative flux is computed. Robustness of the results with respect to changes in the interatomic potentials, dipole functions and reduced mass, as well as to changes in laser pulse parameters (carrier frequencies, timings, phases, field amplitudes, and pulse durations) is investigated.

Through the application of a square CO2 laser beam with uniform energy density distribution to the surface of 123 powder compact, a single piece of ribbon-like plate is produced. This plate may be separated from the powder compact after laser scanning. The width of the plate is approximate to 6 mm, while its thickness is 0.1-0.2 mm. Powder X-ray diffraction indicates that laser-treated samples contain both orthorhombic and tetragonal 123 phases, as well as Y2O3 (200), Y2BaCuO5 (211), BaCuO2 (011), and CuO (001) phases. Scanning electron microscopy reveals a pattern of phase segregation along the transverse cross-section after solidification of the plate. After oxygen annealing of a single ribbon piece, T-c is found to be 90 K. This technique may be applicable to the mass production of 123 bulk superconductor by continuous melting of 123 powders. In addition to its potential for practical applications, the laser technique also helps to explain the complex phases and microstructure formation during melting and solidification of laser-melted 123 liquid. A model relating the microstructure to the thermal history inside the laser-affected region and to the phase diagram of incongruently melting 123 material has been developed to analyse phase formation during laser melting and solidification processes. Reasonable correspondence between theoretical analysis and experimental results was obtained. C1 IOWA STATE UNIV SCI & TECHNOL,AMES LAB,DEPT MAT SCI & ENGN,AMES,IA 50011.

The oxidation mechanism of the composite material was determined by thermogravimetric analysis (TGA) and compositional analysis. Changes in the fracture strength and surface morphology were also determined and related to the oxidation mechanism. Weight changes of samples exposed to flowing Ar with various levels of oxygen partial pressure, P-O2 at 1400 degrees C were monitored continuously with a microbalance. Changes in strength were measured after exposure to flowing Ar with different P-O2 at 1400 degrees C for various periods of time. The P-O2-range employed in this experiment was from 5 x 10(-7) to 1 x 10(-3) MPa. In contrast to the oxidation behaviour of monolithic SiC materials, weight gains were detected for the whole P-O2-range investigated. However, despite the weight gains in the low P-O2-region (P-O2 < 1 x 10(-5) MPa), significant reductions in strength were observed which were apparently due to the loss of SiC whiskers from the sample surface via the formation of volatile SiO. This SiO gas reacted with the Al2O3 matrix to form a non-protective aluminosilicate glass on the surface, resulting in a linear weight gain with time. In the high P-O2-region, typical parabolic weight gains were observed as a result of the formation of an aluminosilicate glass on the surface by a reaction between SiO2, formed by the oxidation of SiC whiskers, and the matrix alumina. The observed increases in strength of the specimens with exposure are believed to be due to blunting of existing surface flaws with a product oxide.

The fibres were continuous, and the volume fractions varied from 0.24 to 0.43. Some of the mechanical-property measurements correlated with the thickness of one of the coating materials, and with microstructural observations of the misorientation angle of the fibres and normalized fibre length. With increasing volume fractions of fibres, the fraction of broken fibres increased. For the PRD-166/glass and PRD-166/SnO2/glass, a substantial fraction of the fibres were misoriented by angles of up to 15 degrees.

This model explains well the effects of donor removal at low fluences, N(eff)(SCR) increase with n-fluence (PHI(n)) at high fluence (''type-inversion'' in SCR), and the increase of resistivity in the ENB with PHI(n). The annealing of each single level with charged state is modeled by an activation energy E(a) which gives the dependence of annealing time constant tau on the annealing temperature. The model describes well the observed effect of RT reverse anneal of N(eff)(SCR), which is probably caused by the difference of annealing time constants of a donor level (long tau) and an acceptor level (short tau). The model also predicts that there is an annealing temperature window, which is about 0-degrees-C, that would freeze the N(eff)(SCR) at the ''minimum'' value for a few years before the reverse anneal. A - 20-degrees-C anneal, however, would freeze N(eff)(SCR) at the as-irradiated value, which is about 1.5-3 times higher than the ''minimum value''. The model also suggests that low resistivity (200 OMEGA cm to 1 kOMEGA cm) starting material may be harder in terms of N(eff)(SCR) for detectors to be within a working window of \N(eff)(SCR)\< 2.5 X 10(12) cm3 (V(fd) = 180 V, 300 mum) after about 1 X 10(14) n/cm2 neutron radiation.

It has been found that the A-center (oxygen-vacancy, E(c) = 0.17 eV) concentration increases with neutron fluence, reaching a maximum at PHI(n) almost-equal-to 5 X 10(12) n/cm2 before decreasing with PHI(n). A broad peak has been found between 200 K and 300 K, which is the result of the overlap of three single levels: the V-V- (E(c) = 0.38 eV), the E-center (P-V, E(c) = 0.44 eV), and a level at E(c) = 0.56 eV that is probably V-V0. At low neutron fluences (PHI(n) < 5 X 10(12) n/cm2), this broad peak is dominated by V-V- and the E-centers. However, as the fluence increases (PHI(n) greater-than-or-equal-to 5 X 10(12) n/cm2), the peak becomes dominated by the level of E(c) = 0.56 eV.

The GLAST proposal is based on silicon strip detectors as the ''technology of choice'' for space application: no consumables, no gas volume, robust (versus fragile), long lived, and self-triggerable. The GLAST detector basically has two components: a tracking module preceding a calorimeter. The tracking module has planes of crossed strip (x, y) 300 mum pitch silicon detectors coupled to a thin radiator to measure the coordinates of converted electron-positron pairs. The gap between the layers (approximately 5 cm) provides a lever arm for track fitting resulting in an angular resolution of < 0.1-degrees at high energy. The status of this R & D effort is discussed including details on triggering the instrument, the organization of the detector electronics and readout, and work on computer simulations to model this instrument.

Numerical results for n = 2, 3 and 4 are consistent with the complete elimination of critical slowing down. Also a heuristic argument is advanced to support the value of z = 0 for the dynamic critical exponent. A new cluster growth algorithm is formulated for the infinite range model that has optimal efficiency of O(N) in the system size N for the Swendsen-Wang update scheme. Using an asymptotically correct version of this cluster method, we are able to perform simulations for the Wolff update scheme up to 262,144 spins for 10(5) time steps for the O(N) models.

The concepts of ionicity and charge transfer are difficult to quantify. However, the changes in bonding in the 50/50 Au-alkali-metal systems between the elemental metals and the compounds are so severe that observations can readily be made concerning their character. The results, as obtained from self-consistent electronic-structure calculations, lead to the apparently odd observation that the electron density at the alkali-metal sites in the compound increases significantly and this involves high l componennts in the charge density. This increase, however, can be attributed to Au-like orbitals spatially overlapping the alkali-metal sites. In a chemical sense, it is reasonable to consider the alkali-metal transferring charge to these Au orbitals. While normally the difference in heats of formation between muffin-tin and full-potential calculations for transition-metal-transition-metal and transition-metal-main-group (e.g., Al) compounds having high site symmetry are small, for the gold-alkali-metal systems, the changes in bonding in the compounds cause differences of approximately 0.5 eV/atom between the two classes of potential. Any serious estimate of the electronic structure in these systems must account for these aspherical bonding charges. The origin of the semiconducting behavior of the heavy-alkali-metal Au compounds is shown to arise from a combination 0 the Au-Au separations and the ionic character of the compounds; the light-alkali-metal Au compounds, with their smaller Au-Au separations, do not have a semiconducting gap. Core-level shifts and isomer shifts are also briefly discussed. RP WATSON, RE (reprint author), BROOKHAVEN NATL LAB,DEPT PHYS,UPTON,NY 11973, USA.

The model has short-range radial forms similar to the tight-binding Hamiltonian of Goodwin, Skinner, and Pettifor but can be utilized in molecular dynamics with a fixed radial cutoff for all structural configurations. In addition to a very good fit to the energy of Si in different bulk crystal structures the model describes very well the elastic constants, defect-formation energies for vacancies and interstitials in crystalline silicon, the melting of Si, and short-range order in liquid silicon.

A scaled Kohn-Sham formalism is applied to treat the electron-electron interaction self-consistently within the local-density approximation. We compare the binding energies of the centered, molecular, and random donor configurations and find that the binding energy is the largest for the centered donor configuration due to the modulation by the boundary condition. We also find that dipole matrix elements can be enhanced if confinement or an external electric field increases the overlap between the initial and final states, and sustains their atomic characters of opposite parity. In addition, we demonstrate the importance of a self-consistent treatment of the electron-electron interaction in determining the ground-state binding energies and charge distributions of the donor states.

Unlike canonical-ensemble simulations, this allows vacancies, interstitials, and substitutional impurities to be treated in a systematic way. The utility of the method is demonstrated by considering the reconstruction of the (110) surface of gold. RP PHILLPOT, SR (reprint author), ARGONNE NATL LAB,DIV MAT SCI,ARGONNE,IL 60439, USA.

The surface shows a large, bond-length-conserving relaxation, which is allowed by the topology of the surface. The relaxation is driven by a rehybridization of the surface Al atoms to sp2, and an accompanying drop in the energy of occupied surface states, during the relaxation. Displacements of surface atoms from bulk positions are as large as 0.7 angstrom, and should be observable using a low-energy electron diffraction intensity analysis. Full relaxed atomic positions are reported, as well as a wavelength-resolved surface band structure, including orbital characters of surface states.

At 300 K, Au overlayers were clustering on top of the first monolayer of C60, and the stronger Au-Au bonding did not break the underlying long-range close-packed order of C60 molecules. However, Au diffused under the second C60 layer and formed two-dimensional clusters. These clusters provided multiple nucleation sites and the second C60 monolayer was rearranged around them. As a result, the second monolayer granulated. Bonding between the second monolayer and underlying Au clusters, characterized by charge transfer, was evidence that density of states near the Fermi level became higher. Our real-space images clarified some details presented in a recent photoelectron spectroscopy study. C1 SUNY STONY BROOK, DEPT PHYS, STONY BROOK, NY 11794 USA.

These metal island films have an imaginary part of the effective dielectric constant larger than the real part at the wavelength 632.8 nm, which is distinctly different from those of the bulk metals. This indicates that the surface mode supported by these metal island films is not the free-electron surface-plasmon mode but another type of long-range surface mode. This type of surface mode can exist in any metal island film as long as the film has the proper thickness and appropriate boundary layers. C1 RENSSELAER POLYTECH INST,DEPT PHYS,TROY,NY 12181.

The net charge transfer was decomposed into geometrical and ''physical'' components, obtained by the integration of reference and difference charge densities [n(ref)(r) and deltan(r) = n(r) - n(ref)(r)] respectively over regions associated with the host or the intercalant. The reference charge density is the superposition of charge densities for the host and intercalant sublattices treated separately, and the host-intercalant partitioning is defined by the condition that the normal component of the density gradient vanish at the interface. Employing self-consistent local-density-functional-theory calculations based on separable pseudopotentials and a plane-wave basis, we obtained a physical charge transfer of 0.2 (0.35)e and a geometrical charge transfer of 0.55e, which yield a net charge transfer of 0.75 (0.90)e for stage 1 (2).

We identify (many) quasidegenerate configurations that contribute to the quantum ground state. When the characteristic quantum and classical energy scales are roughly equal (the ''intermediate'' quantum regime), we find, consistent with earlier numerical studies, that the ''standard map'' determining the coordinates in the classical ground state is renormalized to an effective ''sawtooth'' map, which determines the expectation values of the coordinates in the quantum ground state. We also discuss the dynamics of the model and estimate the characteristic time for various quantum tunneling effects. C1 KRASNOYARSK TECH UNIV,KIRENSKY INST PHYS,KRASNOYARSK,RUSSIA.

The model is fitted to density-functional theory band structures for silicon in the diamond structure over a number of volumes. It is shown that with only a two-center, orthogonal basis, reasonable total energies can be obtained for many different structures. Thus it eliminates the need to use structure-dependent terms in the total-energy model. C1 GEORGIA INST TECHNOL,SCH PHYS,ATLANTA,GA 30332.

First we discuss the fluid mechanics of relativistic spherical combustion. We then numerically collide many bubbles expanding at a velocity v and calculate the resulting spectrum of gravitational radiation in the linearized gravity approximation. Our results are expressed as simple functions of the mean bubble separation, the bubble expansion velocity, the latent heat, and the efficiency of converting latent heat to kinetic energy of the bubble walls. A first-order phase transition is also likely to excite a Kolmogoroff spectrum of turbulence. We estimate the gravity waves produced by such a spectrum of turbulence and find that the characteristic amplitude of the gravity waves produced is comparable to that from bubble collisions. Finally, we apply these results to the electroweak transition. Using the one-loop effective potential for the minimal electroweak model, the characteristic amplitude of the gravity waves produced is h congruent-to 1.5 x 10(-27) at a characteristic frequency of 4.1 x 10(-3) Hz corresponding to OMEGA approximately 10(-22) in gravity waves, far too small for detection. Gravity waves from more strongly first-order phase transitions, including the electroweak transition in nonminimal models, have better prospects for detection, though probably not by LIGO.

We first generalize the C metric of Einstein-Maxwell theory (a = 0) to solutions corresponding to oppositely charged dilaton black holes undergoing uniform acceleration for general a. We next develop a solution-generating technique which allows us to ''embed'' the dilaton C metrics in magnetic dilaton Melvin backgrounds, thus generalizing the Ernst metric of Einstein-Maxwell theory. By adjusting the parameters appropriately, it is possible to eliminate the nodal singularities of the dilaton C metrics. For a < 1 (but not for a greater-than-or-equal-to 1), it is possible to further restrict the parameters so that the dilaton Ernst solutions have a smooth Euclidean section with topology S2 x S2 - {pt}, corresponding to instantons describing the pair production of dilaton black holes in a magnetic field. A different restriction on the parameters leads to smooth instantons for all values of a with topology S2 x R2. C1 FERMILAB NATL ACCELERATOR LAB,NASA,FERMILAB ASTROPHYS GRP,BATAVIA,IL 60510.

Although transgenic mice expressing human apolipoprotein (a) [apo(a)l have previously been described, they failed to assemble Lp(a) particles because of the inability of human apo(a) to associate with mouse apolipoprotein B (apoB). We isolated a 90-kilobase P1 phagemid containing the human apoB gene and with this DNA generated 13 lines of transgenic mice of which 11 expressed human apoB. The human apoB transcript was expressed and edited in the liver of the transgenic mice. Plasma concentrations of human apoB, as well as low density lipoprotein (LDL), were related to transgene copy number; the transgenic line with the most copies of human apoB had a >4-fold increase in LDL cholesterol compared with nontransgenics and a lipoprotein profile similar to that of humans. When human apoB and apo(a) transgenic mice were bred together, plasma apo(a) in mice expressing both human proteins was tightly associated with lipoproteins in the LDL density region. These studies demonstrate the successful expression of human apoB and the efficient assembly of Lp(a) in mice. C1 LAWRENCE BERKELEY LAB,DIV LIFE SCI,BERKELEY,CA 94720.

The aim of this study was to obtain a reliable structure for the doubly oxidized transient intermediate (termed compound I) in the reaction of cytochrome c peroxidase with hydrogen peroxide. This intermediate contains a semistable free radical on Trp191, and an oxyferryl haem group. Results: Compound I was produced in crystals of yeast cytochrome c peroxidase by reacting the crystalline enzyme with hydrogen peroxide in a flow cell. The reaction was monitored by microspectrophotometry and Laue crystallography in separate experiments. A nearly complete conversion to compound I was achieved within two minutes of the addition of hydrogen peroxide, and the concentration of the intermediate remained at similar levels for an additional half an hour. The structure of the intermediate was determined by Laue diffraction. The refined Laue structure for compound I shows clear structural changes at the peroxide-binding site but no significant changes at the radical site. The photographs were processed with a new software package (LEAP), overcoming many of the former problems encountered in extracting structural information from Laue exposures. Conclusions: The geometry of the haem environment in this protein allows structural changes to be extremely small, similar in magnitude to those observed for the Fe2+/Fe3+ transition in cytochrome c. The results suggest that these molecules have evolved to transfer electrons with a minimal need for structural adjustment. C1 UNIV OXFORD,MOLEC BIOPHYS LAB,OXFORD OX1 3QU,ENGLAND.

We find 300-K lifetimes of greater-than-or-equal-to 2.5 mus (350 ns), and interface recombination velocities of 40 cm/s (250 cm/s) for our OMVPE (MBE) structures. Identical measurements for Na2S and bare surfaces yield interface recombination velocities of 5500 cm/s and 34 000 cm/s, respectively. Free-carrier transport in both types of structures is diffusive with hole mobilities of approximately 350 cm2/V s. C1 SANDIA NATL LABS,ALBUQUERQUE,NM 87185.

The parameters evaluated are the x- and z-components of the dipole moment [D] and the z-component of the perihelion velocity of the captured electron (L x A). The calculated integral values are found to be in reasonable agreement with available experimental results. Components of the dipole moment and [L x A] were also evaluated as a function of projectile scattering angle. Here, rapid variations of the parameters are observed near the Thomas angle that indicate the transition from the hard, large angle collisions between the projectile and target nucleus to the soft, small angle scattering between the projectile and active electron.

Swelling is a strong decreasing function of rising %T; the 10%T hydrogel obtained a 17-fold larger swelling ratio (g of swollen hydrogel/g of dry hydrogel) in pure water compared to the 40%T hydrogel. Good agreement is obtained between measured swelling equilibria in aqueous sodium chloride and that calculated from a Flory-type swelling model including ideal Donnan equilibria provided that an adjustable parameter is introduced into the swelling model for hydrogels in pure water. The experimental results presented here indicate that network-chain interpenetration increases with rising %T. C1 UNIV CALIF BERKELEY, DEPT CHEM ENGN, 1 CYCLOTRON RD, BERKELEY, CA 94720 USA.

Applications are made to the tungsten isotopes 171W and 172W. It is shown that relatively small deformation changes can have a significant effect on the energy spectrum. Considering such deformation changes leads to a much improved agreement with the experimental data for both of the investigated isotopes. C1 OAK RIDGE ASSOCIATED UNIV,UNISOR,OAK RIDGE,TN 37831.

The decay rate lambda was found to be time dependent. In particular there is a transient time of the order of 10(-21) s before the asymptotic limit (exponential regime) is reached. The tunneling time can be defined by the delay in attaining this limit at the outer side of the barrier as compared with the inner side. The method of preparing the initial quasi-stationary state influences neither the transient behaviour of lambda nor its asymptotic value while the energy of this state influences both the transient and the asymptotic regimes. Finally, the asymptotic values were used to test the Gamow formula. A relatively good agreement was found and a deeper understanding of this formula was achieved.

With a stiff equation of state, simultaneous explosion into several nearly-equal fragments (NEFs) in a ring-like manner occurs due to the formation of metastable toroidal nuclei. In contrast, with a soft equation of state, simultaneous explosion into several NEFs in a volume-like manner occurs due to the formation of metastable bubble nuclei. Guided by our BUU model, we propose two signatures: (1) because of the geometries of bubbles and toroids and because of the cold breakup at low temperatures, we predict enhanced cross sections for NEFs at small center-of-mass energies. (2) the coplanarity of these NEFs could carry important information concerning the geometry of the sources. This, in turn, could provide information about the stiffness of the equation of state. Finally, the dependence of these two predictions on the number of test particles, impact parameters, and the initial random seeds are assessed. C1 OAK RIDGE NATL LAB,DIV PHYS,OAK RIDGE,TN 37831.

Many-body perturbation theory is applied to obtain the Compton scattering contribution to the total cross section for double ionization. Compton scattering dominates photoionization above 6 keV. Despite the differences between the two processes, the ratio of double to single ionization by Compton scattering appears to approach the asymptotic value given by photoionization calculations. These ratios are in agreement with recent experiments. C1 OAK RIDGE NATL LAB,OAK RIDGE,TN 37831. RP HINO, K (reprint author), UNIV TENNESSEE,DEPT PHYS & ASTRON,KNOXVILLE,TN 37996, USA.

The activation barrier for the Rh adatom to escape from the impurity trap is 0.95 eV, considerably higher than the self-diffusion barrier on the defect-free surface (0.83 eV). The activation barrier to move between the four equivalent trap sites is 0.76 eV. The increased binding along with a higher Rh desorption field at the trap sites imply a stronger Ir-Rh bond compared to Rh-Rh.

Such symmetry originates in the feature that in the presence of phonons the hopping amplitude turns out to depend on the coupling strength. The states generated by resorting to this new q symmetry exhibit both off-diagonal long-range order and pairing. C1 POLITECN TORINO, DIPARTIMENTO FIS, I-10129 TURIN, ITALY.
