Electronic and atomic relaxation processes in irradiated cryocrystals

Relaxation processes and stability of charge centers in preirradiated cryocrystals doped with atomic and molecular species are discussed. The study was performed combining techniques of spectrally resolved thermally stimulated luminescence (TSL), thermally stimulated exoelectron emission (TSEE) and photon-stimulated exoelectron emission (PSEE). Comparison of the yields of electrons and photons in VUV and visible ranges made it possible to discriminate between reactions of charge carriers and neutral reactive species and find interconnection between atomic and electronic processes of relaxation. The radiative mechanism of electronic relaxation stimulation via an atomic subsystem is verified.
