Abstract
It is shown that the photostimulated luminescence of the KBr-In crystal at room temperature preliminary irradiated in the exciton absorption band arise from three types of close defect pairs. The stimulation spectra a for each pair are investigated. It is shown also that one of these three kinds of defect pairs is {F, In2+}, whereas two other pairs have the electron centre of more complicated nature. It is demonstrated that the KBr-In is an effective radiation storage material for both UV- and X-irradiations.
