Abstract Results of a search for high-spin isomers in W and Os nuclei withN=104–107 are presented. Targets of48Ca and48, 50Ti are bombarded with a pulsed136Xe beam, and delayed gamma-radiation is detected by an array of NaI- and Ge-detectors. Several new isomers, with spin values up to ∼22h, are found in178,180W and180, 182, 183Os. Markedly different decay patterns and hindrance factors are found in the Os isotopes as compared to the expectations based on theK-selection rule valid for axially symmetric nuclei. The findings are ascribed to the onset of triaxial distortions.
