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

Abstract

Levels in ${}_{}{}^{102}{}_{}{}^{}\mathrm{Pd}$ have been investigated by utilizing the ${}_{}{}^{99}{}_{}{}^{}\mathrm{Ru}(\alpha , n; \gamma ){}_{}{}^{102}{}_{}{}^{}\mathrm{Pd}$ reaction. The basic measurements were $\gamma$-ray excitation functions, angular distributions, and $\gamma -\gamma$ coincidences. All $\gamma$-ray measurements were performed with Ge(Li) detectors. The excitation functions were used to identify ${}_{}{}^{102}{}_{}{}^{}\mathrm{Pd}$ $\gamma$ 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 $\gamma$-ray cascade connects states of spin $0^{+}$, $2^{+}$, $4^{+}$, $6^{+}$, $8^{+}$, and ${10}^{+}$.
