In particular, during the past decade, the experimental data on the shell evolution of nuclei far from the stability line bloomed a series of works focused on the corresponding tensor effects in both the nonrelativistic and relativistic density functional theories (DFT). In a series of recent works, we identified the tensor force up to the 1/M2 order in each meson-nucleon coupling in the relativistic Hartree-Fock (RHF) theory, by the nonrelativistic reduction for the relativistic two-body interactions. The effects of tensor force on various nuclear properties can now be investigated quantitatively, which eventually allows fair and direct comparisons with the corresponding results in the nonrelativistic framework. | | | Contact Person 所内联系人 | |
