Abstract : The differences, by many orders of magnitude, between the escape-frequency factors obtained in thermoluminescence measurements and the frequency of the lattice vibrations are discussed. It is shown that various processes can be formulated by kinetic equations mathematically identical with those given by Randall and Wilkins but with other pre-exponential factors replacing the frequency factor. Two such processes are proposed: one in which the concentration of conduction electrons increases exponentially with temperature, and one in which the transitions between trapping levels and luminescence centers occur within localized centers.
