Multiplicity of the StatisticalγRays following (O16,xn) Reactions

The multiplicity ${\overline{M}}_S$ of the statistical $\gamma$ rays following several (${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$,$\mathrm{xn}$) reactions has been measured. A correlation between the total $\gamma$ multiplicity ${\overline{M}}_T$ and ${\overline{M}}_S$ was found. This effect is attributed to an increase in the mean excitation energy above the yrast line with increasing angular momentum input.
