S>The effect of scavengers, pressure, temperature, and added xenon on the vapor phase gamma -radiolysis of azomethane is investigated. Most of the results can be explained on the basis of free radical reactions similar to those occurring in the photolysis of azomethane. Values for the ratio of rate constants k/sub 1//k/sub 2//sup 1/2/ or the reactions CH/sub 3/ + CH/sub 3/N/sub 2/CH/sub 3/ yields CH/sub 4/ + CH/sub 2/N/sub 2/CH/sub 3/ (1) and CH/sub 3/ + CH i yields C/sub 2/H/sub 6/ (2) determined from the radiolysis data are in excellent agreement with values based on photolysis experiments, indicating that methane and ethane are formed by the reactions of thermalized methyl radicals. The results are best explained on the basis of the decomposition of an electronically excited molecule, formed either by direct excitation or by ionization followed by neutralization. Ion decomposition and ion-molecule reactions of the usual type are shown to be inconsistent with the results. (auth)
