Abstract
The dependence of the number of point defects on the dose and on the wavelength of the exciting radiation has been studied in uv-irradiated alkali halides. The existence of various types of traps for the stabilization of defects and the occurrence of competition between these traps were assumed. Theoretical expressions were derived for the number of defects induced by the monochromatic uv radiation. These expressions were found to agree with the experimentally measured dose dependences, as well as the thermoluminescence excitation spectra. They included various previously derived functions as special cases. The observed superlinear dose dependence of the intensities of most glow peaks in NaCl is explained by the proposed mechanism.
