| Abstract: | High-spin levels in189Hg have been populated via the175Lu(19F, 5n) reaction. A rotation-aligned band built on a 13/2+ state originating from theνi 13/2 subshell is identified which is interpreted within the framework of “quasiparticle+rotor” models. A negative parity band built on a 21/2? state which can be accounted for by a three quasi-particle state is also observed. |
