Abstract
Optical spectroscopy and EPR are employed to study a beta -PbF2 crystal dop ed with Yb3+ ions. The presence of only one paramagnetic center, the Yb3+ i on with cubic symmetry, is established. Its optical lines are identified, t he empirical system of energy levels is constructed, and the phenomenologic al crystal field potential is determined. The information on the phonon spe ctrum of the beta -PbF2 crystal is obtained from the electron-vibrational s tructure of the optical absorption and luminescence spectra.
