Abstract

The absorption spectra of KCl single crystals irradiated with electrons and protons at energies of 15 and 100 keV and a particle flux ranging from 5×1012 to 1015 cm−2 are investigated. The absorption bands attributed to simple (F, Fa, K) and complex (M, R2, R4, N) color centers are identified in the spectra. The correlation dependences of the absorption coefficients for M, R2, and R4 centers on the absorption coefficient of F centers and the correlation dependences of the absorption coefficients for R2 and R4 centers on the absorption coefficient of M centers are established. The oscillator strengths are calculated for M, R2, and R4 color centers.
