Abstract

Energy spectra, angular distributions, and elemental yield distributions have been measured for products Z = 1−9 produced in the reactions of 12C on 12C. A total reaction cross section 1170−100+170 mb was determined from the measured elemental cross sections and the principle of charge conservation. This total reaction cross section is about 250 mb less than the geometric cross section and agrees with the Glauber-model calculations of DeVries and Peng. The experimental energy spectra, angular distributions, and yield distributions were compared with those from model calculations for the statistical decay of the products of fusion and of incomplete fusion reactions. For both types of calculations, a modified version of the code LILITA was used. By comparing the data to model calculations, an upper limit of 75 mb for the fusion cross section was determined. That limit corresponds to an upper limit of Lcrit for fusion of 10ħ in the sharp-cutoff approximation. The dominant reaction mechanisms appear to be incomplete fusion processes.
