Abstract

High-spin states in ⁸⁶Mo were studied by means of the fusion evaporation reaction ⁵⁸Ni(³²S,2p2n) ⁸⁶Mo 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 T₂ = 1 nucleus ⁸⁶Mo 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=O) 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.
