The distribution of carbon-11 activity in the products resulting from the (n,2n) activation of carbon-12 in benzene was studied. The Li/sup 7/(d,n)Be/ sup 8/ reaction using cyclotron deuterons was used as the source of fast neutrons. A synthesis product, toluene-C/sup 11/, was isolated by carrier methods. The labeled benzene and toluene fractions were separated and purified by gas-liquid partition chromatography (g. l. c.). About 4.5 and 2.2% of the total activity produced were accounted for in benzene and toluene, respectively. Added radical scavengers decreased the activity as benzene-C/sup 11/ but did not significantly affect the formation of toluene-C/sup 11/. Change of phase from liquid to solid had the same effect. The activity as benzene-C/sup 11/ increased with decrease in temperature in the solid state. The results are discussed in the light of the current hypotheses on the chemical effects of nuclear transformations. Chemical mechanisms are considered for the formation of with the results of the study of N/sup 14/(n,p)C/sup 14/ reaction in benzene. (auth)
