| Abstract: | Both the thermal lifetimes of the F′(F′A) centers and the ratios of the electron trapping cross-sections of (FA) to α(αA) centers were derived from the decay kinetics of flash-produced F′(F′A) bands. In particular, the ratios dropped steeply with the temperature possibly due to a thermally activated de-excitation following excited state pre-trapping of the electron by the anion vacancy. |
