High-spin states in Os have been studied using the 
Yb(
C,4n) reaction at a beam energy of 65MeV. Previously known 1-quasiparticle bands have been extended to higher spins. New high-
bands based on 3- and 5-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 5008keV has been found with a half-life of 18(2) ns. The hindrance in decays of the high- intrinsic states are discussed in terms of the 
tunneling model where the low- and high- states interact through the triaxial shape fluctuation.
