Gamma-ray linear polarization measurements following heavy-ion bombardment of odd isotopes of Pd

$\gamma$-ray linear polarization measurements have been used to locate negative parity states in the even-odd isotopes ${}_{}{}^{99,101,103}{}_{}{}^{}\mathrm{Pd}$. A Compton polarimeter based on two Ge(Li) coaxial detectors was used. Collective bands ($I={\frac{11}{2}}^{-}, {\frac{15}{2}}^{-}, {\frac{19}{2}}^{-}, \dots$) built on ${\frac{11}{2}}^{-}$ states were observed in ${}_{}{}^{101}{}_{}{}^{}\mathrm{Pd}$ and ${}_{}{}^{103}{}_{}{}^{}\mathrm{Pd}$. Many negative parity states were also observed in ${}_{}{}^{99}{}_{}{}^{}\mathrm{Pd}$, but they do not appear to be part of a similar collective band. These polarization measurements also confirm many angular momentum assignments which previously had been made using systematic arguments.
