英文摘要Excited states have been observed for the first time in the neutron-deficient nucleus Ba-117 using the recoil-decay tagging technique following the heavy-ion fusion-evaporation reaction Zn-64(Ni-58, 2p3n)Ba-117. Prompt. rays have been assigned to Ba-117 through correlations with beta-delayed protons following the decay of A = 117 recoils. Through the analysis of the gamma-gamma coincidence relationships, a high-spin level scheme consisting of two bands has been established in Ba-117. Based on the systematics of the level spacings in the neighboring barium isotopes, the two bands are proposed to have nu h(11/2)[532]5/2(-) and nu d(5/2)[413]5/2(+) configurations, respectively. The observed band-crossing properties are interpreted in the framework of cranked shell model.
