Compton Profile of LiH

Abstract

Self-consistent electron wave functions were calculated previously for the LiH crystal in the cell approximation in connection with a study of positron annihilation in diatomic crystals. The Compton profile of LiH derived from these wave functions is compared with recent measurements. It is concluded that the self-consistent cell approximation to the electronic structure in LiH accounts for the principal features of the x-ray structure factors, the Compton profile, and the positron annihilation spectra.
