Systematic study of two-proton radioactivity half-lives using the two-potential and Skyrme-Hartree-Fock approaches *

In this work, we systematically study the two-proton($2p$) radioactivity half-lives using two-potential approach while nuclear potential is obtained by Skyrme-Hartree-Fock with Skyrme effective interaction of {SLy8}. For true $2p$ radioactivity($Q_{2p}$ $>$ 0 and $Q_p$ $< $0, where $Q_{2p}$ are released energy one-proton two-proton radioactivity), standard deviation between experimental our theoretical calculations {0.701}. addition, extend model to predict 15 possible candidates taken from evaluated atomic mass table AME2016. The calculated results indicate that a clear linear relationship logarithmic $\rm{log}_{10}T_{1/2}$ coulomb parameters [ ($Z_{d}^{0.8}$+$l^{0.25}$)$Q_{2p}^{-1/2}$] considered effect orbital angular momentum proposed Liu $et$ $al$ [Chin.
