Neutron resonance spectroscopy of ${}^{106}\mathrm{Pd}$ and ${}^{108}\mathrm{Pd}$ from 20 to 2000 eV

Parity nonconserving asymmetries have been measured in $p$-wave resonances of ${}^{106}\mathrm{Pd}$ and ${}^{108}\mathrm{Pd}$. The data analysis requires knowledge of the neutron resonance parameters. Transmission and capture $\gamma$-ray yields were measured for $E_n=20\mathrm{}$–2000 eV with the time-of-flight method at the Los Alamos Neutron Science Center (LANSCE). A total of 28 resonances in ${}^{106}\mathrm{Pd}$ and 32 resonances in ${}^{108}\mathrm{Pd}$ were studied. The resonance parameters for ${}^{106}\mathrm{Pd}$ are new for all except one resonance. In ${}^{108}\mathrm{Pd}$ six new resonances were observed and the precision improved for many of the resonance parameters. A Bayesian analysis was used to assign orbital angular momentum for the resonances studied.
