ResumoThe absolute cross sections for a number of different reactions resulting from the bombardment of $^{61}\mathrm{Ni}$ with 38.5, 41.0, 43.5, 46.0, 48.5, and 51.0 MeV $^{16}\mathrm{O}$ ions were determined from $\ensuremath{\gamma}$-ray yields observed from the decay of resulting radioactivities, and from yields of in-beam $\ensuremath{\gamma}$ rays. The total cross section was compared to an optical-model calculation. The relative population of the reaction products was compared to calculations for the statistical decay of a compound nucleus by $n$, $p$, and $\ensuremath{\alpha}$ evaporation. This model does account for the general features of the experimental results, and agrees reasonably well with the stronger exit channels.NUCLEAR REACTIONS: $^{61}\mathrm{Ni}(^{16}\mathrm{O}, X)$, ${E}_{^{16}\mathrm{O}}=38.5, 41.0, 43.5, 46.0, 48.5, \mathrm{and} 51.0$ MeV; measured ${E}_{\ensuremath{\gamma}}$, ${I}_{\ensuremath{\gamma}}$; deduced $\ensuremath{\sigma}(E)$.
