Proton inelastic scattering on the transitional nucleusNd144

Abstract

The nucleus ${}_{}{}^{144}{}_{}{}^{}\mathrm{Nd}$ is studied via the ${}_{}{}^{144}{}_{}{}^{}\mathrm{Nd}$(p,p’) reaction with 35 MeV protons. Angular distributions are measured for 13 states; 12 are assigned ${\mathit{J}}^{\mathrm{\pi }}$=$2^{+}$, $3^{\mathrm{-}}$, $4^{+}$, or $5^{\mathrm{-}}$. The present results are useful in understanding the nuclear shape transition taking place in the range N=82–90 and in the investigation of a proposed mixed symmetry mode in ${}_{}{}^{144}{}_{}{}^{}\mathrm{Nd}$.
