摘要：

Relativistic effects are employed to describe the weakly bound nuclei, e.g. He, Be, C and O near closed shells. In order to calculate the energy levels of the ground states and first excited states for these nuclei, we present a description based on the assumption of a two-body system formed by a neutron added to an inert core. We adopt the appropriate interaction between neutron and inert core which is a modified of Yukawa potential. Then we solve the Dirac equation with pseudospin symmetry in the shell model by using the basic concept of the supersymmetric shape-invariance method. The results obtained from this approach are compared with experiments and do not show any inversion in agreement with experiments.
