Abstract

The evaluation of site symmetry distortion for an impurity ion in cubic crystals is a problem which obtained attention from a number of investigators during the last decade. So far, all approaches were based on multi-parameter fittings of the experimental results by some theoretical curves. A new technique, described in this paper, makes it possible to obtain the site symmetry distortion parameter in a straightforward fashion directly from the experimental data. The method is based on precise measurements of the light polarization azimuth for a beam transmitted by a crystal with reorienting centres. results are reported for FA(Li) centres in KCl and RbCl. © 1995 Società Italiana di Fisica.
