摘要：
The optical and paramagnetic absorption spectra of MgO:Mn crystals of different origin, irradiated in a reactor, have been investigated. It is found that, in spite of only a small amount of Mn2+ impurity ions in the investigated crystals, their influence on the efficiency of formation and accumulation of F+-centers is dominant. The dependence of the number of F+-centers both on irradiation dose and on manganese concentration is studied.
