An investigation was carried out on the x ray and uvinduced creation of the color centers, bleaching action of x rays, and thermal destruction of the color centers in NaCl single crystals. It was shown that the velocity of the creation of F- and V-centers depends on the degree of plastic deformation and on previous irradiation. The number of uv-created F-centers passes through a maximum value that is proportional to the number of F-centers created during previous irradiation. Bleaching action of x rays and excitons on the 390-, R-, M- , and N-bands in natural NaCl crystals previously x irradiated and partially bleached in F-band was detected. During the heating of the x-irradiated natural crystals a complicated reciprocal transformation of color centers takes place as a result of ionic processes. (auth)
