Kopsavilkums

In this paper, we analyzed experimental annealing kinetics of the primary electronic F centers and dimer F₂ centers observed in MgF₂ at higher radiation doses and temperatures. The developed phenomenological theory takes into account the interstitial ion diffusion and recombination with the F₂-centers, as well as mutual sequential transformation with temperature growth of three types of experimentally observed dimer centers: F₂(1), F₂(2), F₂(3) (which differ tentatively by charges (0, +1, +2) with respect to the host crystalline sites). The results of the electron, neutron and ion irradiation are compared. As the result, the relative initial concentrations of three types of F₂ electronic defects before annealing are obtained, along with energy barriers between their ground states as well as the relaxation energies.
