Effect of F → M phototransformation on aquoluminescence from γ-irradiated sodium chloride

Abstract

F → M phototransformation in γ-irradiated NaCl was found to be accompanied by a lower intensity of aquoluminescence and a greater liberation of I₂ during the dissolution of the sample in water and in KI solution, respectively. The results are explained on the basis of the different reactions of F and M centres with water during dissolution yielding e^–_aq due to F and (e^–2₂)_aq, a dimer or (e^–_aq+e^–_aq) and some complex species due to M centres.
