Abstract
In this paper some relations between dielectric properties of diagonal cubic ionic crystals are derived on the basis of the shell model for ions of Dick and Overhauser. The relations, which contain no model constants, are in a good agreement with experimental data. Also it is shown that Dick and Overhauser overestimated the number of electrons in the shells of the ions, which accounts for the failure of their quantitative treatment. In the appendix the paper of Hanlon and Lawson on the same subject is discussed.Keywords
