The optical bleaching of F centers in gamma-irradiated KCl at various dosage was measured. The amount of F centers which bleached quickly, denoted by Nq, was studied as a function of irradiation dose and bleaching temperature. It was found that N_q includes the decrease of F center concentration due to complex center formation and due to recombination with positive holes, that the latter part of N_q is closely related to the F centers formed in the first stage of gamma-irradiation, and that the complex centers are only formed by the bleaching of F centers formed in the second stage of irradiation. The rate of complex center formation by intermittent light pulses was studied, the results indicating that the amount of complex centers formed by a given number of pulses depends on the time interval between successive light pulses.
