Abstract

High-spin states in ¹⁸⁵Os have been studied using the ¹⁷⁶Yb(¹³C,4n) reaction at a beam energy of 65 MeV. Previously known one-quasiparticle bands have been extended to higher spins. New high-K bands based on three-quasiparticle excitation have been identified. Nilsson configurations are assigned based on the g factors deduced from M1/E2 branching ratios within the bands, In addition, a new isomer at 5007 keV has been found with a half-life of 18(2) ns. The hindrance in decays of the high-K intrinsic states are discussed in terms of the 7 tunneling model where the low-K and high-K states interact through triaxial shape fluctuation.
