Abstract In the “naive” but fairly successful model by Bodenstedt and Perscheid, the electric field gradient (EFG) in a hcp s-p metal is first evaluated by the lattice sum method, postulating a conduction electron charge shift and approximating the new conduction electron distribution by point charges. Adding to this EFG, a contribution due to the anisotropy of lattice vibrations, i.e. (〈z 2〉−〈x 2〉), was presumed to give the total temperature-dependent EFG. We find, however, from the EFG results of the present calculation for111CdCd and the original result for67ZnZn, that the experimental data are better represented without the addition of the anisotropic vibration term. This finding, as well as the outline of the present evaluation of 〈z 2〉 and 〈x 2〉 and hence the EFG for Cd, are discussed.
