Abstract

摘要

The tensor force is one of the most important components of the nucleon-nucleon interaction and plays a critical role in the shell evolution in exotic nuclei. 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/M2order 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.
