Description

Nuclear structure information serves as important inputs for the study of nuclear astrophysics, for example, the equation of state for neutron star, and the nuclear masses and decay rates for nucleosynthesis . Nowadays ab initio methods have been paid more and more attention since they study nuclear structure from the realistic nucleon-nucleon (NN) interaction, which can be obtained either from high precision NN scattering data or eventually from the first principle QCD. As the only ab initio method available in the relativistic scheme, the relativistic Brueckner-Hartree-Fock (RBHF) theory has been raised in the 80s and shows many advantages in the study of nuclear matter such as saturation mechanism. In this work, we extend the RBHF theory to finite nuclei and study the ground state properties of double magic nuclei as a first step. The binding energy and charge radius are close to experiment. By strictly taking the relativistic effect into account, the present study reproduce the spin-orbit splitting from the bare NN interaction in a self-consistent way. Furthermore, the present self-consistent RBHF calculation provides a solid benchmark for various studies using local density approximation.
