Abstract
A method for calculating the electronic polarizability of ions in optical s ingle-axis crystals is presented. It is shown that the mixed ionic-covalent type of interionic bond leads to considerable anisotropy of the electronic polarizability of the O2- ion. The principal components of the electronic polarizability tensor of the O2- ion and the probable value of the electron ic polarizability of the Nb5+ ion in LiNbO3 are calculated.
