Description
The phonon and quasiparticle structure of the low-lying states in 188,190,192Os is investigated within the microscopic quasiparticle-phonon model. An overall agreement with the data is obtained for energies and transitions. The properties of the 0+ states are found to be correlated with the evolution of the nuclear shape toward the γ-soft region. Special attention is devoted at the 43+ state. This state is found to be composed of a large double-γ phonon component coexisting with an even larger one-phonon hexadecapole piece. Such a mixed phonon structure explains the observed, apparently contradictory, properties of the 43+ states in Os isotopes
