The creation of F-, Mg+ and Mg0 centers in Mg-doped crystals during thermal neutron irradiation was studied experimentally and theoretically. The concentrations of F- and Mg+ centers were measured by using optical absorption techniques, while the Mg0 center concentration was measured by using photoluminescence techniques. It was found that the experimentally measured dose dependences of F- and Mg+ center production were well predicted by the calculations, whereas the experimental data for Mg0 were shifted uniformly with respect to the theoretical curve. This was attributed to the detailed formation mechanism for this defect.
