#### Abstract

Proton and neutron single particle level spacings are determined for the $A=146\mathrm{}$ mass region, using a rotationally invariant interaction and recent experimental data. Excitation energies of spherical and deformed high spin states in ${}_{}{}^{147}{}_{}{}^{}\mathrm{Gd}$, the transition probability $B(E2;{10}^{+}\to {8}^{+})$ for several $N=82\mathrm{}$ isotones, and the ${0}^{+}$ excited state spectra of, and neutron pair transfer probabilities for, levels in ${}_{}{}^{146}{}_{}{}^{}\mathrm{Gd}$ and ${}_{}{}^{144}{}_{}{}^{}\mathrm{Sm}$ are calculated. Comparisons with experimental data are made.
