Mapping the proton drip line from [formula omitted] to [formula omitted

Abstract

The structure of proton drip line nuclei in the 60<A<100 mass range is studied with the relativistic Hartree–Bogoliubov (RHB) model. For the elements which determine the astrophysical rapid proton capture process path, the RHB model predicts the location of the proton drip-line, the ground-state quadrupole deformations and one-proton separation energies at and beyond the drip-line. The results of the present theoretical investigation are compared with available experimental data. For possible odd- Z ground-state proton emitters, the calculated deformed single-particle orbitals occupied by the odd valence proton and the corresponding spectroscopic factors are compared with predictions of the macroscopic–microscopic mass model.
