Abstract


The even-even nuclei, near the the N=90 quantum shape phase transition, of cerium, neodymium and samarium isotopic chains were placed in the interacting boson model symmetry triangle. The different trajectories of the chains revealed the increasing γ-dependence from samarium to cerium by decreasing Z, which can be associated with the decreasing sharpness of the transition from spherical to deformed structures.

Keywords


N=90 quantum shape phase transition; critical point; IBM-1 calculations; IBM symmetry triangle
