Pulse radiolysis of transient defects in KBr at high temperatures

The annealing of the F and V4 centers created by a short electron pulse between 400 K and 700 K has been studied. The annealing of the F centers is found to consist of three stages : two bimolecular decays and a monomolecular decay, which has the longest decay time constant. The temperature dependence of the reaction rate constants and the correlation between the annealing of the F centers and interstitial centers are obtained
