Moments of inertia of triaxial nuclei in covariant density functional theory

The covariant density functional theory (CDFT) and five-dimensional collective Hamiltonian (5DCH) are used to analyze the experimental deformation parameters and moments of inertia (MoIs) of 12 triaxial nuclei extracted by Allmond and Wood [J. M. Allmond and J. L. Wood, \href{doi.org/10.1016/j.physletb.2017.01.072}{Phys. Lett. B \textbf{767}, 226 (2017)}].

It is found that the CDFT MoIs are generally smaller than experimental values but show qualitative consistency with irrotational flow and experimental data for the relative MoIs, supporting that the intermediate axis has the largest MoI. It is further found that the collapse of pairing interaction can lead to the nuclei behave like a rigid-body flow as exhibited in the cases of \ce{^{186-192}Os}}.
