Distributions of the total energy and multiplicity of gamma rays feeding the discrete yrast states in heavy-ion-induced fusion reactions

The distribution of the total energy and multiplicity of gamma rays feeding the yrast transitions has been measured for ${}_{}{}^{158}{}_{}{}^{}$,159Er, ${}_{}{}^{130}{}_{}{}^{}\mathrm{Ce}$, and ${}_{}{}^{116}{}_{}{}^{}$,117Te, which are produced in several heavy-ion fusion reactions. The observed shape of the distribution feeding discrete yrast states varies with the spin of the yrast transition. However, the differences are small, especially for heavier-ion induced reactions.
