Abstract

DISLOCATIONS in alkali halide crystals doped with silver ions can be ‘decorated’ by a hydrogen treatment, which causes reduction and subsequent precipitation of silver1. In the course of work on the kinetics of this solid state reaction, the problem arose of deducing the reaction constant and the activation energy without exact knowledge of the reaction mechanism, which is rarely discussed in the literature.
