Abstract : Penn's model of an isotropic semiconductor is used to calculate epsilon (q), the diagonal part of the static microscopic dielectric function. Penn's results have been extended beyond q = K sub F. This region is important in developing a quantum theory of lattice vibrations of diamond and zinc-blende crystals. Explicit results are given for the range 0 < q < 4K sub F. (Author)
