Level Structure ofPd102Investigated by (α, xn; γ) Reactions

Abstract

Levels in $^{102}\mathrm{Pd}$ have been investigated by utilizing the $^{99}\mathrm{Ru}(\ensuremath{\alpha}, n; \ensuremath{\gamma})^{102}\mathrm{Pd}$ reaction. The basic measurements were $\ensuremath{\gamma}$-ray excitation functions, angular distributions, and $\ensuremath{\gamma}\ensuremath{-}\ensuremath{\gamma}$ coincidences. All $\ensuremath{\gamma}$-ray measurements were performed with Ge(Li) detectors. The excitation functions were used to identify $^{102}\mathrm{Pd}$ $\ensuremath{\gamma}$ rays, and the coincidence measurements were used to construct a level scheme. Nuclear spins have been inferred from analysis of the angular distributions. The proposed level scheme contains 24 levels; the dominant $\ensuremath{\gamma}$-ray cascade connects states of spin ${0}^{+}$, ${2}^{+}$, ${4}^{+}$, ${6}^{+}$, ${8}^{+}$, and ${10}^{+}$.
