Abstract Using time-resolved pulsed absorption and luminescence spectroscopy we have studied the creation ofF 2 centers during electron pulses of nanosecond duration in the temperature range 80 to 300 K. We show that the formation ofF 2 centers in long-lived metastable states is thermally activated and competes withF 2 center relaxation to the singlet state. It is shown that the S-T crossing in the set of states which describe theFC2 center lies above the1 П u level. We propose that when the crystal is excited with the lowest energy quanta which produce a photocurrent, the formation of tripletF 2 centers takes place by localization of a conduction electron on anF 2 + center.
