Abstract

High-spin states have been studied in neutron-deficient 54114Xe, populated through the 58Ni(58Ni,2p) fusion-evaporation reaction at 230 MeV. The Gammasphere γ-ray spectrometer has been used in conjunction with the Microball charged-particle detector in order to select evaporation residues of interest. The yrast band has been greatly extended to a tentative spin of 52hℏ and shows features consistent with smooth band termination. This band represents the first evidence for a core-excited (six-particle, two-hole) proton configuration above Z = 53.
