Abstract


In the model of line-ionic crystal thermal radiation induced processes in coloured crystals of CaF2-Na, irradiated at 80 K ionizing radiation are investigated. In the temperature range 80-300 K concentrations decline curves are studied VK, VKA (1), FA, FA (1) – growth centers and VKA and MA+-centres. It is shown that in crystals CaF2-Na defects dipole relaxation of coloured crystal type is due to recombination processes. In crystals with thermally nonequilibrium point defects recombination processes are absent and the total concentration of colour centers in the crystal is heated from 80 K to 300 K remains constant.
