Abstract

A method is developed for determining the mean lifetime of anion vacancies in dielectric crystals following irradiation. This method is used to study the temporal kinetics of the concentrations of vacancies and F 2 + color centers in lithium fluoride crystals irradiated by ionizing radiation. It is then possible to study the dependences of the vacancy lifetime on the concentration of F 1 color centers, temperature, and impurity content of a crystal. Vacancy and F 2 + color lifetimes determined by this method are given.
