Abstract
Excited states have been observed for the first time in the neutron-deficient nucleus using the recoil-decay tagging technique following the heavy-ion fusion-evaporation reaction (, 2p3n). Prompt rays have been assigned to through correlations with -delayed protons following the decay of recoils. Through the analysis of the coincidence relationships, a high-spin level scheme consisting of two bands has been established in . Based on the systematics of the level spacings in the neighboring barium isotopes, the two bands are proposed to have and configurations, respectively. The observed band-crossing properties are interpreted in the framework of cranked shell model.
