Abstract : Continued study of simple lattice defects in single-crystal IIA oxides was carried on, utilizing previous methods (ESR and optical spectroscopy) plus some new methods of magneto-optical spectroscopy. The spectral Faraday rotation associated with the main visible and u.v. absorption bands in neutron-irradiated MgO and CaO was surveyed; this enabled the characterization of the several such bands as due to either paramagnetic or diamagnetic centers. The magneto-optic nature of the F bands in MgO and CaO, at 4.9 and 3.7 e.v. respectively, showed the F centers involved to be analogous to those in alkali halides, with negative p-state spin-orbit coupling. The zero phonon line of the CaO F center was identified by the magneto-optic double resonance method. In a separate project, the charge-transfer reaction F - F' was studied in CaO:Ca crystals.
