Proton drip-line nuclei in relativistic Hartree-Bogoliubov theory

Ground-state properties of spherical even-even nuclei $14<~Z<~28$ and $N=18,20,22$ are described in the framework of relativistic Hartree-Bogoliubov (RHB) theory. The model uses the NL3 effective interaction in the mean-field Lagrangian, and describes pairing correlations by the pairing part of the finite range Gogny interaction D1S. Binding energies, two-proton separation energies, and proton rms radii that result from fully self-consistent RHB solutions are compared with experimental data. The model predicts the location of the proton drip line. The isospin dependence of the effective spin-orbit potential is discussed, as well as pairing properties that result from the finite range interaction in the pp channel.
