Unified description of rotational-, $γ$-, and quasiparticle-band structures in neutron-rich mass $\sim$ 110 region

Band structures of the neutron-rich Mo- and Ru-isotopes around A $\sim$ 110 are investigated using the triaxial projected shell model (TPSM) approach employing multi-quasiparticle configuration space. The mass region under investigation depicts a rich variety of band structures with well developed $γ$- and $γγ$-bands, and quasiparticle excitations based on them. It is demonstrated that TPSM provides a reasonable description of most of the observed properties, in particular, detailed structure variations observed in Mo-isotopes are well reproduced in the present work.
