Systematic features of signature inversion of (h11/2)p(i13/2)n bands in doubly odd nuclei around A~160.

Based on the arguments of excitation energy systematics and alignment additivity rule, the spins of the lowest observed states of the (${\mathit{h}}_{11/2}$${)}_{\mathit{p}}$(${\mathit{i}}_{13/2}$${)}_{\mathit{n}}$ bands in $^{156}\mathrm{Tb}$, $^{158}\mathrm{Ho}$, $^{166}\mathrm{Lu}$, and $^{168}\mathrm{Ta}$ are assigned as 8, 9, 8, and 9 instead of the previous assignments of 6, 6, 7, and 10, respectively. Taking these new spin assignments and the preliminary experimental results of $^{162,164}\mathrm{Lu}$ into account, the systematic features of the signature inversion of the (${\mathit{h}}_{11/2}$${)}_{\mathit{p}}$(${\mathit{i}}_{13/2}$${)}_{\mathit{n}}$ bands of the doubly odd nuclei in the lighter rare-earth region (around A\ensuremath{\sim}160) are presented.
