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.
