“…It is possible, e.g., to compare the distribution function vTSL(E) of a TSL process after y-irradiation with the distribution function qEPR(E) determined from EPR measurements on the recombination reactions of the radicals after y-irradiation of the same material, see, e.g. [14].…”

An algorithm is presented which allows the estimation of the distribution of activation energy from measurements of thermally stimulated processes, such as radical recombination reactions, thermally stimulated luminescence (TSL), and thermally stimulated depolarization or current. This algorithm starts with the characteristic activation function of the process under consideration and the measurement regime. The applicability of the mathematics is extensively discussed. Activation energy distributions of radical reactions and TSL are calculated for different polymers.
