摘要: High-spin states in Mo-86 were studied by means of the fusion evaporation reaction Ni-58(S-32,2p2n) at 135 MeV beam energy. Charged-particle-gamma gamma and -gamma coincidences recorded with early implementation GAMMASPHERE array MICROBALL charged-particle detection system used to largely extend level scheme T-tau=1 nucleus a possible spin I=24h 13 excitation The is compared neighboring nuclei. There evidence for enhanced shell-model influence 4 quasiparticle region (I=12-16h). observed (pi=+,alpha=0) sequence I greater than or equal 16 h appears be associated triaxial collective rotational band. This interpretation supported calculations within configuration-dependent shell-correction approach cranked Nilsson potential. (Less)
