Abstract

Excited states in [Formula Presented] have been identified for the first time using the [Formula Presented] evaporation channel from the [Formula Presented] reaction at a beam energy of 250 MeV. The experiment was carried out using GAMMASPHERE coupled to the MICROBALL charged-particle detector array and an array of 15 neutron detectors. Two collective structures were observed with the yrast band built on the [Formula Presented] configuration. Comparisons of the yrast-band energies with the excitation energies of the yrast states in even [Formula Presented] and in odd [Formula Presented] and [Formula Presented] isotopes for [Formula Presented] were analyzed, revealing different responses of the underlying cores to the valence [Formula Presented] and [Formula Presented] orbitals. It is concluded that the neutron [Formula Presented] valence orbital has a larger influence than that of the proton [Formula Presented] valence orbital.
