Abstract
On X-irradiation, cobalt-doped NaCl crystals show a new relaxational loss peak, designated as an S peak. The S loss peak occurs on the higher frequency side of the A and B loss peaks observed in unirradiated crystals. The intensity of the S loss peak increases with the dose of X-irradiation and with the concentration of cobalt. The dc conductivity and heights of A and B loss peaks decrease with the creation of S centres. On heating the X-irradiated crystals to about 200 degrees C, the S centres disappear and the conductivity and the heights of the A and B peaks are partially restored to their original value. A possible method for S centres is mentioned.Keywords
