Effect of the spin-orbit interaction on the structure and two-proton radioactivity of 18Mg

By the SHFB calculations, the single-proton energy spectra, proton density distributions of the individual orbitals near the Fermi energies, 2p decay energies (Q2p), spectroscopic factors versus different W values can be calculated. Then, within the mean-field cluster potential approach, the diproton cluster potentials with different W values are extracted. Finally, using the Wenzel-Kramers-Brillouin approximation by inputting different Q2p values, the 2p decay half-lives with and without the spectroscopic factors versus different W values are obtained.
