Ground-state properties of deformed proton emitters in the relativistic Hartree-Bogoliubov model

The relativistic Hartree-Bogoliubov (RHB) model is applied in the description of ground-state properties of proton-rich odd-Z nuclei in the region 53 less than or equal to Z less than or equal to 69. The NL3 effective interaction is used in the mean-field Lagrangian, and pairing correlations are described by the pairing part of the finite-range Gogny interaction D1S. The model predicts the location of the proton dripline, the ground-state quadrupole deformations and one-proton separation energies at and beyond the drip-line, the deformed single-particle orbitals occupied by the odd valence proton, and the corresponding spectroscopic factors. The results of fully self-consistent RHB calculations are compared with available experimental data, and with predictions of the macroscopic-microscopic mass model.
