摘要：
The relaxation of F2+ centers in radiation-colored crystals of lithium fluoride starting from the moment of the coaction of pulsed UV irradiation and a shock wave is investigated. It is shown that the annealing curve of these centers displays a nonmonotonic character at room temperature and is a consequence of three + processes. The first two are the processes of disintegration of unstable (short-lived) and stable F2+ centers, and the third process involves the formation of stable centers upon a random encounter of appropriate constituents in the course of their diffusive wandering over the lattice.
