摘要

The level structures of ^130-136Ce are analyzed with the available experimental data. The level energies, E2 moments and the ratios for transitions from the and 0₂ bands are compared with the values from the Dynamic Pairing plus Quadrupole model and the Interacting Boson Model-1. In ¹³⁰Ce, the recently assigned 1.672 MeV state is tentatively associated with on the basis of the predicted K-components and the decay mode. The 2.068 MeV state is associated with of this band. In ¹³²Ce, the 1932 keV level is associated with band. Variation of the nuclear structure with neutron number N is studied vis-脿-vis the symmetry and critical point symmetries and . The effect of filling of up-sloping Nilsson orbitals on the decreasing deformation with increasing N is illustrated.
