Abstract：
Due to the contributions of the quantum vacuum to densities, the relativistic Hartree approach for finite nuclei produces a large effective nucleon mass m IM_N≈0.8, which causes the spin-orbit force to be only 1/3 of the empirical value. In this work we introduce tensor couplings for the vector mesons. Consequently, the spin-orbit force is enhanced by a factor of 2 while a large effective nucleon mass remains. The nucleon spectra of shell-model states are ameliorated evidently. The predicted anti-nucleon spectra in the vacuum are deepened about 20-30MeV.
