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

The relativistic Hartree-Bogoliubov (RHB) model is applied in the descripti on 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 interac tion is used in the mean-field Lagrangian, and pairing correlations are des cribed by the pairing part of the finite-range Gogny interaction D1S. The m odel predicts the location of the proton dripline, the ground-state quadrup ole deformations and one-proton separation energies at and beyond the drip- line, the deformed single-particle orbitals occupied by the odd valence pro ton, 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.
