The band structure and triaxial shape in 118Xe

Abstract High-spin states of 118 Xe have been investigated by means of γ-ray spectroscopy using the 92 Mo( 29 Si,2pn) reaction at a bombarding energy of 110 MeV. Several new side bands as well as the yrast band were established. The first band crossings both in the yrast sequence and in the even-spin sequence of the γ-band were observed at ħω c = 0.39 MeV and ħω c = 0.31 MeV respectively. The γ-dependent cranked shell-model calculation was performed to interpret the band crossing in the γ-band.
