| Abstract: | The temperature dependence of the stress-induced polarization of F center luminescence is calculated for the simplest vibronic model for the relaxed excited state, in which 2s and 2p electronic states interact in cubic symmetry via a triply degenerate odd-parity vibrational model. The 2s state is assumed lower in energy than 2p by |Esp|. A lower bound for |Esp| can be determined for those alkali halides for which this polarization has been found experimentally to be independent of temperature. |
