“…Several successful theoretical approaches have been conducted to obtain the half-lives of proton emitters such as the Wentzel-Kramers-Brillouin (WKB) approximation using a Woods-Saxon-type potential added to the Coulomb potential [20], the fully self-consistent calculation based on relativistic density functionals [29], the generalized liquid-drop model (GLDM) [30], the single-folding model (SFM) [4], the two-potential approach (TPA) [2], the Coulomb and proximity potential model (CPPM) [25,31], the perturbative approaches such as the distorted-wave Born approximation (DWBA) [32], and the self-consistent calculation based on relativistic density functional [33].…”

Proton radioactivity and α-decay half-lives of neutron-deficient nuclei have been systematically studied. The proton-nucleus interaction potential is developed by single folding the density distribution of the daughter nuclei with the effective M3Y-Paris nucleon-nucleon (NN) interaction. The penetrability is calculated with the Wentzel-Kramers-Brillouin approximation. The applicability of the universal decay law on the proton decay half-lives has been examined and a new set of parameters has been identified. The competition between α-decay and proton radioactivity of neutron-deficient nuclei has been investigated. The proton radioactivity is found to be the dominant mode of decay for nuclides located very close to the proton drip-line. The effect of using different microscopic proton and neutron density distributions on the half-lives for these two decay modes is studied. It is found that the calculated half-lives with the microscopic densities that obtained from the self-consistent Hartree-Fock-Bogoliubov method successfully reproduce the experimental data. The impact of nuclear deformation on the half-lives is investigated for these two decay modes. The influence of nonlocality through the finite-range exchange part of the NN interaction on the α-decay process is elucidated. Our theoretical calculations have been confirmed experimentally and satisfactory agreement has been achieved.
