Abstract
Basic properties of the simplest radiation defect, the F+ center (an oxygen vacancy with a trapped electron), in the simplest oxide material (MgO with a cubic lattice structure) remain for a long time a subject of discussion, in light of highly contradictory literature data. In this paper, new data on the electron paramagnetic resonance (EPR) and optical absorption measurements for the neutron- and energetic-ion-irradiated (70 MeV Ar) MgO single crystals are discussed. Theoretical analysis of the diffusion-controlled F+ center isochronal annealing is performed; the obtained migration energies for oxygen interstitials are discussed in light of the available calculations on the mobility of both neutral and charged oxygen interstitials in metal oxides.
