Two-proton radioactivity of exotic nuclei beyond proton drip-line

Proton radioactivity of neutron-deficient nuclei with atomic numbers [Formula: see text]–91 and mass number 104–211 is investigated using the analytical super-asymmetric fission (ASAF) model — a model used to study [Formula: see text]-decay and cluster radioactivity since 1984. The experimental [Formula: see text] values are compared with calculated ones based on WS4 (Y. Z. Wang et al., 2014–2015), and in few cases KTUY05 (H. Koura et al., 2005) mass models. Proton drip-line and neutron drip-line are determined using the WS4 mass model. We compare the calculated results with experimental half-lives, showing good agreement.

Good Agreement

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.
