Abstract：
The pseudospin symmetry is systematically investigated by solving the Dirac equation with an (scalar and vector) Woods-Saxon potential. We find that the splittings of pseudospin energy and the lower component of pseudospin doublets are sensitive to the nuclear radius and the nuclear diffusivity, but to the depth of nuclear potential. The splitting of pseudospin energy with larger n or l is more sensitive to the values of the parameters. The energy level crossing is also found for some pseudospin partners with variation of the nuclear mean field. With the increasing of nuclear radius and nuclear diffusibility, the splitting of the lower component of pseudospin doublets diffuses toward the nuclear surface and reaches the largest value on the nuclear surface. The splitting of pseudospin doublets increases with increasing nuclear diffusibility but decreases with increasing nuclear radius and the depth of nuclear potential. Because the variations of the parameters R and V₀are related with the number of nucleon and the characteristics of nuclear surface can be described by the parameter of diffusibility, the conclusions obtained are meaningful for analyzing nuclear properties.
