Radiation-induced color centers with new properties in lithium fluoride crystals subjected to thermal shocks or compression

Abstract

It has been established that in lithium fluoride crystals, subjected to pre-irradiation thermal shocks or compression, intrinsic point defects with new properties different from the known properties of the usual defects of the same composition are formed as a result of irradiation. The obtained new properties are similar to those for radiation-induced defects that were previously registered in nanocrystals and called near-cluster defects. It is shown that the combination of pre-irradiation heating and compression of a crystal increases the ratio of the concentrations of formed near-cluster and usual defects.
