Show affiliationsWe propose an extended band-mixing formalism capable of describing the structure of the ground- and γ-bands in a wide range of collective spectra beyond the regions of well-deformed nuclei. We apply it to explain the odd–even staggering effect observed in the γ-bands of Mo, Ru and Pd nuclei and to obtain on this basis a consistent interpretation of new experimental data in the neutron rich region. As a result the systematic behaviour of the staggering effect, together with the mutual ground–γ-band disposition, interband mixing and intraband level spacing are explained as the manifestation of respective changes in nuclear collectivity.
