  Within the collective Bohr Hamiltonian, the adoption of a mass tensor as a
function of collective coordinates has demonstrated its importance for
describing the structure of nuclei. On the other hand, for odd-mass nuclei, the
Coriolis interaction between the rotational and single-particle motions affects
significantly the structure of nuclear excited states. In the framework of a
recently developed extended Bohr Hamiltonian, by considering the
Deformation-Dependent Mass Formalism whith different mass parameters for the
rotation and the two \betha and \gamma vibrations and taking into account the
Coriolis contribution, we investigate the bands structure of the 173Yb, 163Dy,
155Eu and 153Eu nuclei. Excited-state energies and B(E2) transition
probabilities are calculated and compared with the available experimental data.
Besides, we investigate the effect of DDMF and the Coriolis force on nuclear
observables.
