Özet
The gas-chromatographic analysis of benzene-iodine solutions containing molecular iodine-125 after various storage times showed that no radiolytic products appeared while some products such as benzene, iodobenzene, biphenyl, and iodobiphenyl, were detected under the same analytical conditions in our recent studies concerning the reactions of iodine atoms activated by L shell photoelectric ionization in benzene-iodine solutions, and the self-radiolysis of iodobenzene labelled with iodine-12515. On the other hand, our theoretical calculations showed that if iodine molecules were uniformly distributed in benzene, iodobenzene should be detected as a radiolytic product due to the local absorption of Auger electrons of iodine-125. The absence of any radiolytic product clearly demonstrated that iodine aggregates have an important role in the absorption of Auger electrons of iodine-125 in benzene-iodine solutions. In addition, theoretical calculations showed that if the iodine aggregation is taken into account the experimental result agrees well with theoretical calculations. © 1987 Akadémiai Kiadó.
