Properties of Excited States of Pd and Cd Nuclei by Coulomb Excitation

Abstract

We have Coulomb-excited the first-excited ($2^{+}$) states of most even-even nuclei of Pd and Cd using enriched targets. Three of these states were previously unknown (${\mathrm{Pd}}^{108}$, ${\mathrm{Pd}}^{110}$, and ${\mathrm{Cd}}^{116}$). We also observed excited states in ${\mathrm{Pd}}^{105}$, ${\mathrm{Cd}}^{111}$, and ${\mathrm{Cd}}^{113}$, the latter yielding a new level at 290 kev. Transition probabilities (lifetimes) for these transitions have been determined and show definite systematic trends.
