Times Cited Count:15 Percentile:62.9(Physics, Nuclear)High-spin states in Os have been studied using the Er(O,4n) reaction at a beam energy of 85 MeV. Several new negative parity levels including a 48-ns isomer have been identified. Nilsson configurations for the levels are assigned by comparison with multi-quasiparticle calculations. Potential-energy-surface calculations show an increasing influence of triaxiality in nuclear shapes at higher spins. The decay rate of the isomer is discussed in relation to the role of the quantum number.

Times Cited Count:20 Percentile:73.84(Physics, Nuclear)High-spin states in Os have been studied using the 170Er(18O,5n) reaction at a beam energy of 85 MeV. Nine rotational bands based on 1-, 3-, 5- and 7-quasiparticle excitations have been observed. Nilsson configurations are assigned for the newly observed bands using g-factors deduced from M1/E2 branching ratios within the bands. In addition, two isomers with K=(43/2+) and (43/2-) have been identified. The K=(43/2+) isomer decays directly to the K=9/2+ ground state band with a large difference in the quantum number, 17. The decay rates are disccused in terms of a tunneling model where high- (isomeric) and low- states interact via fluctuations towards triaxial nuclear shapes.
