The dependence of the formation cross-sections for the two levels on bombarding energy was studied in each case. The results are compared with theoretical curves predicted from the statistical model and the evaporation theory as used by Huizenga and Vandenbosch. In each case agreement between theory and experiment is found to be reasonable if the parameter sigma describing the variation of level density with spin has the value 4 plus or minus 1.
