Lattice parameter data obtained from experiments at the National Synchrotron Light Source at the Brookhaven National Laboratory are also presented here. The vacancy formation energy of fcc 4He at 10.4 cm3 /mol was obtained ...

X-ray reflectivity measurements have been performed for an investigation of the structure of Ag films deposited in situ on Ge(111) over the thickness range of 3--15 monolayers. The films deposited at a substrate temperature ...

The first main chapter is a report of the results of calculations which^allow the temperatures of the electrons and the ions to differ and which^include electron thermal conduction. The calculation is done in spherical^geometry, ...

The mixed layered compounds K$\sb{\rm 1-x}$Rb$\sb{\rm x}$C$\sb8$ and K$\sb{\rm 1-x}$Rb$\sb{\rm x}$C$\sb{24}$ represent quasi two-dimensional alloys interleaved by graphite hexagonal planes. We report extensive x-ray ...

Extended x-ray absorption fine struture (EXAFS) spectra have been obtained for a group of layered transitional-metal dichalcogenide crystals, including the nonstoichiometric compounds Ti(,1+x)Se(,2) and the alloys ...

Measurements of integrated intensities of X-ray Bragg reflections have been made as a function of temperature on two large single crystal specimens of solid krypton. These data have been interpreted in terms of a Debye ...

The growth of Pd(,2)Si thin films from electron beam evaporated Pd films on Si(lll) substrates has been studied using X-ray diffraction techniques. In situ layer growth kinetics were measured over a temperature range of ...

At low densities the helium solids are highly quantum in nature, with the small atomic mass and weak interactive forces giving rise to large vibrational motions of the atoms about their mean lattice sites. While these ...
