Abstract In the present work, considering the preformation probability of the emitted two protons in the parent nucleus, we extend the Coulomb and proximity potential model (CPPM) to systematically study two-proton (2p) radioactivity half-lives of the nuclei close to proton drip line, while the proximity potential is chosen as Prox.81 proposed by Blocki et al. in 1981. Furthermore, we apply this model to predict the half-lives of possible 2p radioactive candidates whose 2p radioactivity is energetically allowed or observed but not yet quantified in the evaluated nuclear properties table NUBASE2016. The predicted results are in good agreement with those from other theoretical models and empirical formulas, namely the effective liquid drop model (ELDM), generalized liquid drop model (GLDM), Gamow-like model, Sreeja formula and Liu formula.

In this work, we systematically study the two-proton ([Formula: see text]) radioactivity half-lives of nuclei close to the proton drip line within a modified Gamow-like model. Using this model, the calculated [Formula: see text] radioactivity half-lives can well reproduce the experimental data. Moreover, we blackuse this model to predict the [Formula: see text] radioactivity half-lives of 22 candidates blackwhose [Formula: see text] radioactivity is energetically allowed or observed but not yet quantized in evaluated nuclear properties table NUBASE2016. blackThe predicted results are in good agreement with the ones obtained by using Gamow-like model, effective liquid drop model (ELDM), generalized liquid drop model (GLDM) as well as a four-parameter formula.
