Assignment of a heavy-ion produced high-spin cascade to a Rh isotope

A $\gamma$-ray cascade with side chains previously assigned to ${}_{}{}^{99}{}_{}{}^{}\mathrm{Pd}$ and recently shown to occur in a nuclide with $Z\le 45$, is unambiguously assigned to ${}_{45}{}^{}{}_{}{}^{}\mathrm{Rh}$. Particle-$\gamma$ coincidence measurements on the ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ + ${}_{}{}^{90}{}_{}{}^{}\mathrm{Zr}$ and ${}_{}{}^{11}{}_{}{}^{}\mathrm{B}$ + ${}_{}{}^{91}{}_{}{}^{}\mathrm{Zr}$ reactions at 56 and 40 MeV, respectively, identify transitions in coincidence with charged particles to allow the elemental assignment. Systematics indicate the probable isotope is ${}_{}{}^{99}{}_{}{}^{}\mathrm{Rh}$.
