Abstract
A report is given on simultaneous measurements of thermally stimulated exoelectron emission (TSEE) and thermoluminescence in alkali halides X-irradiated at about 77 K, by using a clean high vacuum system. Intensities of the TSEE glow peaks below 270K are found to be much stronger than those obtained by using a diffusion-pump system. It is also reported that TSEE glow curves of the specimens cleaved in air and in a vacuum are different from each other.
