Coriolis contribution to excited states of deformed ${}^{163}\mathrm{Dy}$ and ${}^{173}\mathrm{Yb}$ nuclei with multiple mass parameters

The use of different mass parameters for the rotation and two vibrations in the Bohr Hamiltonian is important for describing properties of nuclei, especially interband $E2$ transition probabilities. For odd nuclei, the Coriolis interaction of the angular momentum of an odd nucleon with that of a nucleus can affect results noticeably. Excited-state energies and $E2$ transition probabilities have been calculated for the ${}^{163}\mathrm{Dy}$ and ${}^{173}\mathrm{Yb}$ nuclei, by using three different mass parameters and taking into account the Coriolis interaction, once shell-model calculations have been performed to determine the single-particle ground-state properties of ${}^{163}\mathrm{Dy}$ and ${}^{173}\mathrm{Yb}$.
