Summary

The lower-lying electron energy bands in CsAu arising from the levels of the valence electrons of the constituent atoms are computed using the method of matching wave functions at the surfaces of the atomic polyhedrons surrounding each atom. The radial parts of the wave functions required are determined by the quantum defect method. CsAu is assumed to be completely ionic. Calculations sre carried out for the points in k-space at the center of the first Brillouin zone and at its extrema in the STA100! and STA111! directions. The calculations indicate that CsAu is a semiconductor, in agreement with experiment, with a minimum energy gap, which is vertical, of sbout 2.3 ev located at the extremum of the STA111! direction of the first zone. Limitations and some possible extensions of the calculations are discussed. (auth)
