Abstract
Within the framework of a realistic theoretical model, diffusion of hot holes in alkali-halide crystals prior to self trapping is shown to have a substantial influence on the time dependence of the flux of desorbed ground state neutral metal atoms resulting from pulsed electron beam bombardment of these crystals. Comparison of results from the model with new time dependent measurements of Li ESD from LiF suggest that substantial hot hole diffusion occurs in LiF, and that, depending on its preparation, the LiF surface can be an absorber or reflector of hot holes.
