Abstract：
The tensor coupling of the ω meson to nucleon in modified derivative scalar coupling (MDSC) model for finite nuclei was investigated. In addition to the spin-orbit splittings improved by the tensor coupling, our results show that the tensor force (or the effect of the tensor coupling) shows attractive in the interior of nuclei, and then becomes repulsive in the surface region. As a result, the single-particle states are more bound for very deeplying orbits, and less bound for those very near the Fermi energies.
