Identification of γ transitions in ${}_{}{}^{147}{}_{}{}^{}\mathrm{Ba}$, ${}_{}{}^{149}{}_{}{}^{}\mathrm{Ce}$, and ${}_{}{}^{151,153}{}_{}{}^{}\mathrm{Nd}$

The γ transitions in ${}_{}{}^{147}{}_{}{}^{}\mathrm{Ba}$, ${}_{}{}^{149}{}_{}{}^{}\mathrm{Ce}$, and ${}_{}{}^{151,153}{}_{}{}^{}\mathrm{Nd}$ have been identified from γ-γ-γ, γ-γ, x-γ, and x-γ-γ coincidence studies of spontaneous fission of ${}_{}{}^{252}{}_{}{}^{}\mathrm{Cf}$. The yrast positive parity band in ${}_{}{}^{149}{}_{}{}^{}\mathrm{Ce}$ is assigned to an ${\mathit{i}}_{13/2}$, neutron favored signature. The yrast negative parity band in ${}_{}{}^{149}{}_{}{}^{}\mathrm{Ce}$ is assigned a ${\mathit{h}}_{9/2}$ proton favored signature. The positive parity band in ${}_{}{}^{151}{}_{}{}^{}\mathrm{Nd}$ corresponds to the positive parity band in ${}_{}{}^{149}{}_{}{}^{}\mathrm{Ce}$. The negative parity band in ${}_{}{}^{153}{}_{}{}^{}\mathrm{Nd}$ corresponds to the negative parity bands of ${}_{}{}^{149}{}_{}{}^{}\mathrm{Ce}$ and ${}_{}{}^{161}{}_{}{}^{}\mathrm{Er}$. The band observed in ${}_{}{}^{147}{}_{}{}^{}\mathrm{Ba}$ is built on the ${\mathit{h}}_{9/2}$ orbital. The plots for ${\mathit{J}}_1$ in these isotopes are remarkably similar, supporting our assignments. © 1996 The American Physical Society.
