Abstract
The microscopic dielectric function epsilon (q) of germanium was calculated using a pseudopotential scheme. Fifteen bands and 23040 points were included in the sampling of the Brillouin zone 14.67+or-0.4 was obtained from the simple Penn model. The Fourier components of the charge density and the histogram of the density of states are also presented. The comparison with experiment gives good agreement.Keywords
