Abstract

The post-irradiation decay of electrons trapped in low-temperature glasses has been analyzed either in terms of tunnelling models which invoke direct transfer of electrons from initial solvent traps to acceptors or in terms of a first order reaction with a time-dependent rate constant of the form\(k(t) = Bt^{\alpha ^{ - 1} } \), O<α≤1. This particular form of time-dependent rate constant was believed to be unique for the CTRW model of MONTROLL and WEISS. It is shown that the time-dependent rate constant calculated from the tunnelling models can be adequately approximated by this particular form with O<α≤0.1.
