Abstract
Three single-site structure-independent approximations for the electronic band structure of a condensed material are considered. The results of these methods when applied to copper are compared with the known results belonging to the Burdick potential as calculated for crystalline copper. In each case the dispersion relation may be said to be 'fair' but the approximate single-particle density of eigenstates is completely unsatisfactory.Keywords
