Accumulation of F centers in alkali-halide crystals at room temperature

Research output: Contribution to journalArticlepeer-review


1. We have shown that in both "solution" and "melt" KCl and KCl-PbCl2 crystals the main contribution to the fast accumulation of F centers arises from a common source -divacancies. The action of this source, operating in accordance with a noncatalytic mechanism, with due allowance for the possibility of the direct formation of F centers from the source, may be described by the sum of two exponentials. 2. All the experiments involving a high-temperature quench agree closely with the foregoing concept of the dual impurity distribution in the "solution" crystals and the role of preradiation defects in the accumulation of F centers.
