Abstract
Ionic polarizabilities are calculated for alkali, halide, and chalcogenide ions in crystals with the NaCl structure. The Sternheimer method is used to calculate the ionic polarizability. The crystalline environment about the central ion is taken to be a spherically averaged sum of pseudopotentials. The numerical results show that the anion polarizability are affected by their environment, while the cation polarizability are not affected. A final set of ionic polarizabilities are proposed which differ significantly from preceding compilations.
