Abstract
The rapid decay of the excited state of the F centers in KBr:OH- has b een measured by mean of a pump and probe technique with picosecond tim e resolution. The lifetime of the F centers (tau approximately 1 mus a t 77 K) is shortened in the OH- doped samples, to tau approximately 31 0 ps. The quenching of the normal radiative lifetime seems to be relat ed to librational excitation of the OH- molecular ion.
