It has been found that the formation time of Fcenters in the stepwise photoionization of impurity Tl+ ions in KBr is 30 ± 10 ps. This result is evidence that processes corresponding to the formation of F-H pairs in pure crystals may occur during the recombination of an electron with a Tl2+ center in an alkali-halide crystal.
