Annotation:

Experimental and theoretical studies of electron-hole recombination in pure and doped KCl crystals, irradiated with x-rays. It is shown that the pure and mixed with Li+ X-rayed crystals at 77 K discolored light of the F-band at ~10 %, and with the admixture of Na+ – 60 %. Observed a proportional decrease in the concentration of electron and hole centers. Based on the comparison of experimental and calculated data it is concluded that in the process of intensely occur in crystals of electron-hole pairs localized on close between electron and hole centers.

Key words:

recombination, X-rayed crystals, electronic centers, hole centers, electron-hole pairs, the F-band
