摘要
The possible relation between the stored energy and the thermoluminescence in gamma- and electron-irradiated NaCl samples has been studied in detail. It has been found that the thermoluminescence, which only exhibits a single glow peak, always occurs at temperatures higher than the temperature at which the main stored-energy peak appears. It is concluded that different recombination processes are involved in these two phenomena. Plastic deformation and doping with calcium induce a stored-energy spectrum different from the spectrum observed in pure and as-cleaved samples, but the amount of stored energy does not change for a given irradiation dose. It is pointed out that the same type of radiation-induced defects might be annealed in the low-temperature region of the stored-energy spectrum as well as in the peak around 520K.
