Relativistic Hartree-Fock approximation in a nonlinear model for nuclear matter and finite nuclei

Abstract

Scalar field self-interaction terms are included in the framework of a relativistic \ensuremath{\sigma}+\ensuremath{\omega}+\ensuremath{\pi}+\ensuremath{\rho} Hartree-Fock approach to nuclear structure. The model provides a good description of the spin-orbit interaction, total binding energies, and densities, improving previous relativistic Hartree and Hartree-Fock approximations.
