It is shown that the behaviour of the temperature dependence of the critical current in polycrystalline thin films of high-T c superconductors depends crucially on the assumption made concerning the nature of the intergranular material. The usual ass

The luminescent emission of solid argon was measured under state-selective excitation using synchrotron radiation. With the aid of excitation spectra and surface coverage experiments it was possible to show that the higher-energy emission bands at 10

We propose a new method based on small clusters with the constraint of periodic symmetry to compute electron density and ground-state electronic energy of solids. Calculations are carried out on h.c.p. solid helium, and the Hartree-Fock density is sh

Relations between many of the results of recent investigations of superconducting doped lanthanium cuprate and a model expression for the dielectric permittivitye(ω, g) are developed.

For pt.I see ibid., vol.15, p.5033 (1982). The cluster approximation in the unrestricted Hartree-Fock limit is used in a computation of the Na LII,III X-ray edge in NaF. In these computations the appropriate boundary potential discussed by Kunz and K

The connection between fundamental core excitations and X-ray edges in non-metallic solids is reviewed. By means of a cycle of the Born-Haber type which is described herein, a connection is established for an alkali halide crystal between the energy

For pt.II see ibid., vol.15, p.5037 (1982). The energies of key levels of low-lying configurations of the Na atom and the Na+ ion are calculated ab initio with inclusion of the effects of electron correlation. The levels considered are those required
