Systematic Behavior of Quasirotational Bands in Odd-APd Nuclei

Quasi-rotational bands built on the ${\frac{7}{2}}^{+}$ and ${\frac{11}{2}}^{-}$ states in ${}_{}{}^{101}{}_{}{}^{}\mathrm{Pd}$, ${}_{}{}^{103}{}_{}{}^{}\mathrm{Pd}$, and ${}_{}{}^{105}{}_{}{}^{}\mathrm{Pd}$ and the ${\frac{5}{2}}^{+}$ state in ${}_{}{}^{101}{}_{}{}^{}\mathrm{Pd}$ have been excited by (heavy-ion, $\mathrm{xn}$) reactions. ($d, p$) and ($d, t$) reactions have been used to show that the absence of the ${\frac{5}{2}}^{+}$ band in ${}_{}{}^{103}{}_{}{}^{}\mathrm{Pd}$ and ${}_{}{}^{105}{}_{}{}^{}\mathrm{Pd}$ is related to the fragmentation of the $d_{\frac{5}{2}}$ quasiparticle strength in these nuclei. An unusual relation has been found between the type of reaction used and the detection of quasirotational bands in odd-$A$ nuclei.
