✦ Synopsis

Abstract

Calculations are made of optical absorption spectra for the following inhomogeneous colloidal centers of sodium in NaCl: for metallic particles of sodium; particles with oxidized shell; particles with a dielectric unrelaxed shell, as well as the shell in the form of a transitional layer with a low concentration of free electrons acting in plasma oscillations, etc. The experimental observations of the position of the maximum of the absorption band enable the identification of a number of the models studied in irradiated as well as in additively coloured NaCl crystals.

## Abstract It is shown that a better theoretical formulation of the properties of the U~2~ centre in the alkali halides is given in terms of ligand field theory rather than the approach usually adopted, which consists of an application of the techniques employed by Gourary and Adrian [5] in their
