Abstract

Lifetimes of rotational states built on the 7/2-[514] and 1/2-[521] Nilsson single-particle orbitals in 181Os have been measured using the coincidence recoil-distance method. The experimentally determined quadrupole moment, assuming axial symmetry, is ≈20% larger for the 7/2-[514] band compared with the 1/2-[521] band. The difference can be understood as an effect of triaxiality. Total Routhian surface calculations show deviations from axial symmetry for both bands, leading to good agreement between theory and experiment.
