Description
Summary:The impact of an external electric field on electron seizure by neutral traps was studied within the Torrey model of a solvated electron random walk. The step length of the random motion, determined by the free diffusion of a temporarily escaped electron, increases with electric field strength, changing the reaction mechanism from a diffusional to a hopping one. The field dependence of the rate of the hopping reaction essentially differs from that obtained for diffusional trapping. Such a difference may serve for experimental discrimination between the hopping and diffusional mechanisms of this reaction.
