摘要：

The spectrum of F-center creation has been measured for KBr:TI by means of synchrotron radiation (12-24 eV). Analysis of the spectrum reveals the decay of cation excitons (19.7-20.3 eV) with the formation of a double amount of electron-hole pairs. The creation efficiency of a stable F center is especially high at 15-17 eV where the absorption of one photon leads to the formation both of an electron-hole pair and an exciton. In this case there are favorable conditions for stabilization of mobile radiation defects due to the association of interstitial halogen atoms, holes, and cation vacancies.
