• The quasi-bands structure for the transition from spherical to deformed shape in Sm isotopes is studied by making use of the self-consistent collective coordinate method. The five-quadrupole collective coordinates and momenta are explicitly treated and they are canonically transformed into the intrinsic shape and rotational degrees of freedom with respect to the body-fixed reference frame. From the analysis of the collective kinetic energy in the intrinsic system, the higher-order anharmonic terms including the coupling with two-quasi-particle non-collective states play an essential role in the description of the mass parameters and rotational moments of inertia.
