Abstract
During an investigation of anionic diffusion in lead and silver bromide, the kinetics of bromine release into vacuum under irradiation from U.V. light was observed. Both materials display an initial linear release with time (t) which then changes into a √t dependence. Both materials exhibit a temperature sensitivity to the release kinetics but differ in their response. These results will be discussed with reference to current ideas on AgBr and PbBr2 photodecomposition theories.
