Thermally stimulated relaxation in NaF X-irradiated at room temperature

Abstract

The thermally stimulated processes in NaF X‐irradiated at room temperature are studied. Three processes are observed whose relative weight depends on the F‐coloring stage: (1) electron release; this causes glow peaks to appear at 75 and 115°C, as a result, M+ centers are annealed out; (2) interstitial fluorine release from different traps and subsequent recombination with F‐centers and F‐aggregate centers, it causes glow peaks at 70, 130, 200, 240, and 280°C; (3) F‐center migration causing their annealing by recombination with interstitials or the formation of F‐aggregate centers.
