Abstract

We carried out the three-dimensional cranking calculations for osmium ${}^{182}{Os}$ within the Hartree-Fock-Bogoliubov framework. It turned out that the state in the $g$ -band is stable (unstable) with respect to the tilt angle of the cranking axis when the angular momentum is below (above) a critical value. However, the states in the $s$ -band with the angular momentum below $30 ℏ$ are unstable everywhere along the band. In our model calculations, the wobbling motion does not exist on top of the $s$ -band state characterized by the component of two aligned particles.
