Solid benzene at -160 deg C was irradiated with singly charged C/sup 1// sup 4/ ions at 5000, 90, and 45 ev. The volatile products of irradiation were analyzed by gas-liquid chromatography in conjunction with internal-flow proportional counting. The yields of three products of the irradiations C/sup 1// sup 4/-labeled benzene, toluene, and cycloheptatriene) were found to decrease with decreasing ion energy. At a given ion energy the yields of those compounds were found to increase with decreasing energy density (ev per target molecule). It was found that the toluene-C/sup 1//sup 4/ produced in this work had the same ring methyl distribution of activities as that formed from C/sup 1//sup 4/ nuclear recoil labeling in benzene-2-methylpyrazine solution. Some speculative considerations are proposed in regard to the mechanism of formation of these products. In addition to benzene, toluene, and cycloheptatriene, the following C/ sup 1//sup 4/-labeled compounds were identified as products of the irradiations: allene, propyne, 1, 2-butadiene, 1, 3-butadiene, 1 and (or) isobutene, and 1- butyne. Trace amounts of n-butane and indirect evidence for propane were observed. (auth)
