Abstract
High-spin states in were studied by means of the fusion evaporation reaction S,2p2nMo at 135 MeV beam energy. Charged-particle-γγ and -γγγ coincidences recorded with the early implementation of the GAMMASPHERE array and the MICROBALL charged-particle detection system were used to largely extend the level scheme of the =1 nucleus to a possible spin of I=24ħ at 13 MeV excitation energy. The excitation scheme is compared to neighboring nuclei. There is evidence for enhanced shell-model influence in the 4 quasiparticle region (I=12–16 ħ). The observed (π=+,α=0) sequence at spin I≥16ħ appears to be associated with a triaxial collective rotational band. This interpretation is supported by calculations within the configuration-dependent shell-correction approach with the cranked Nilsson potential. © 1996 The American Physical Society.
