Abstract

High-spin states have been populated in ${}^{102}{Pd}$ by ${}^{92}{Zr} ({}^{13}C, 3 n γ) {}^{102}{Pd}$ with $E_{lab} = 56$ MeV and in ${}^{100}{Pd}$ by ${}^{91}{Zr} ({}^{12}C, 3 n γ) {}^{100}{Pd}$ with $E_{lab} = 63$ MeV. We find in each nuclide a ground state band $Δ J = 2$ of positive parity extending to $J^{π} = 14^{+}$ , as well as two negative parity bands $Δ J = 2$ , one of odd spin and one of even spin. For ${}^{100}{Pd}$ , the present level scheme represents the first definitive study of excited states in this nuclide. For ${}^{102}{Pd}$ the present data include the first measurement of the $γ$ -ray linear polarizations. The level energies are compared to the variable moment of inertia model, the interacting boson approximation model, and to the results of a quasiparticle calculation.
