Isotope effects in the yields of H-and D-atoms in acid, neutral and alkaline matrices lwe been studied bp EPR merhods. In acid matrices the isotope effect is the same in UV-and X-irmdiated matrices, but in neutral and alhaline m&rices the effect is Iarger in UV-irradiated matrices. Furthermore, \hen the If-and D-atoms are formed by photobleaching of trapped electrons the isotope effect is stron& dependent on the \r.tve!ength of the bleachins light. increasing ~ifh increasing xae-Iengths-The isotope effect in sulphuric acid matrices is dependent on the concentrstion of the acid. The obser\ations are brief& discussed.

The decay oi H-atoms in several y-irradiated aqueous solutions was examined by ESR spectroscopy from 'U°K to 150°K. In perchloric acid the decay indicates the presence of two trapping sites. The more strongly trapped H-atoms decay by a first-order process, apparently resulting from a slow release fr
