摘要：
High-spin states in Os-184 have been studied using the Er-170(O-18,4n) reaction at a beam energy of 85 MeV. Several new negative parity levels including a 48-ns K-pi=(18(-)) isomer have been identified. Nilsson configurations for the levels are assigned by comparison with multiquasiparticle calculations. Potential-energy-surface calculations show an increasing influence of triaxiality in nuclear shapes at higher spins. The decay rate of the K-pi=(18(-)) isomer is discussed in relation to the role of the K quantum number.
