Abstract : The relatively high efficiency of production of free radicals which become stabilized at liquid nitrogen temperature during the radiolysis of several aromatic hydrocarbons demonstrates the quantitative importance of these intermediates in the mechanism of radiation decomposition. The required measurement of G(R.) values necessitated the indirect approach of comparing partially saturated ESR absorption spectra at high powers and then evaluating the extent of saturation in an independent measurement. g9r.0 values are: benzene, 0.32; toluene, 0.53; biphenyl and naphthalene, 0.10. The results average about one-third of the corresponding values for radiolysis at room temperature. (Author)
