Core coupled states inEu145

Abstract

New high-spin states in ${}_{}{}^{145}{}_{}{}^{}\mathrm{Eu}$ up to 4 MeV excitation energy have been studied with the methods of the inbeam $\gamma$-spectroscopy bombarding enriched ${}_{}{}^{142}{}_{}{}^{}\mathrm{Nd}$ targets with ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$ ions. For most of them a configuration is proposed in terms of weak coupling one proton hole to the ${}_{}{}^{146}{}_{}{}^{}\mathrm{Gd}$ core or one proton particle to the ${}_{}{}^{144}{}_{}{}^{}\mathrm{Sm}$ core.
