Abstract

The phonon dispersion curves and binding energies of Rb, Cs, and Ba have been calculated using Harrison's modified point ion pseudopotential with two adjustable parameters. The exchange and correlation effects in the Hartree dielectric function have been adequately considered. The theoretical results are found to be in good qualitative agreement with the experimental results.

## Abstract The nonlocal pseudopotential formalism of Harrison is applied to the problem of binding energies, structures, and lattice constants of nine simple metals. The formulation of the crystal potential is similar to that given by Harrison, but the Kohn‐Sham approximation is used for the descr
