Abstract
The temperature dependence of the electric field gradient in noncubic metals is calculated within a pseudopotential approach including the influence of lattice vibrations. The resulting factorizes into a Debye-Waller factor and a lattice sum over screened ions. The accurately measured values for In, Cd, Zn, Sb, and Sn are quantitatively reproduced using known data for the lattice constants and for the mean-square atomic displacements.
