The γ-radiolyses of cyclohexane and 2,2,4-trimethylpentane have been reinvestigated. Bromobenzene was used as the electron scavenger. The analysis of the G-values of benzene obtained at high concentrations of bromobenzene showed that the empirical formula proposed by Hummel for the electron scavengingG=G_fi+G_gi{1-exp(-√‾αS)}is better than that proposed by Warman et al.The values of Gfi+Ggithus obtained were 3.7±0.3 for cyclohexane and 3.5±0.2 for 2,2,4-trimethylpentane. The bromobenzene-concentration dependence of the G-values of hydrogen and methane from 2,2,4-trimethylpentane was well explained by the hypothesis that the lifetimes of the 2,2,4-trimethylpentane ion for the decomposition are in the same order as the time needed for the geminate recombination. |
