The Peculiarities of the Radiation Defects Formation Kinetics in the Case of Defect Complexes Genesis

The problem of determination of radiation defects accumulation kinetics is considered under the assumption of defects complexes formation, particlularly, the ones of anion and cation vacancies. Based on the system of differential equations, the analytical expression for doze dependencies of concentrations of defects and their complexes are obtained. As it is shown, the enrichment of the crystal by the defects with higher formation cross-section and the simultaneous depletion by the defects with lower one are taking place at sufficiently high fluences of radiation (about 1018 cm—2).
