Non-yrast states inPd101and their rotational interpretation

Several non-yrast states of both parities in ${}_{}{}^{101}{}_{}{}^{}\mathrm{Pd}$ have been observed using three-detector $\gamma -\gamma$ coincidence measurements following the reaction ${}_{}{}^{92}{}_{}{}^{}\mathrm{Zr}({}_{}{}^{12}{}_{}{}^{}\mathrm{C}, 3n){}_{}{}^{101}{}_{}{}^{}\mathrm{Pd}$. Energy levels, $\gamma$-ray mixing ratios, and branching ratios are deduced from the data and compared with the results of a rotational model calculation. Five of the newly discovered states are identified as non-yrast members of rotational bands based on the $\frac{5}{2^{+}}$ and $\frac{11}{2^{-}}$ states.
