Abstract：
Pseudospin symmetry and spin symmetry in the relativistic square well are investigated systematically by solving the Dirac equation with scalar and vector potentials and are found to be a good approximation in realistic nuclei such as ²⁰⁸Pb. The pseudospin breaking and spin breaking are shown in correlation with nuclear mean field. The square well radius plays an important role in the splittings of energy and wavefunction. The dependence of splittings with quantum numbers is also analyzed.
