“…Their calculated results are in agree well with the known experimental data. Recently, Cui et al studied the 2p radioactivity of the ground state of nuclei based on a generalized liquid drop model (GLDM) [37], in which the 2p radioactivity process is described as a pair particle preformed near the surface of the parent nucleus penetrating the barrier between the cluster and daughter nucleus. In this view, 2p radioactivity shares the similar theory of barrier penetration with different kinds of charged particles' radioactivity, such as α decay, cluster radioactivity, proton radioactivity and so on [38][39][40][41][42][43].…”

In the present work, combining with the Geiger-Nuttall law, a two-parameter empirical formula is proposed to study the two-proton (2p) radioactivity. Using this formula, the calculated 2p radioactivity half-lives are in good agreement with the experimental data as well as the calculated ones obtained by Goncalves et al. ([Phys. Lett. B 774, 14 (2017)]) using the effective liquid drop model (ELDM), Sreeja et al. ([Eur. Phys. J. A 55, 33 (2019)]) using a four-parameter empirical formula and Cui et al. ([Phys. Rev. C 101: 014301 (2020)]) using a generalized liquid drop model (GLDM). In addition, this two-parameter empirical formula is extended to predict the half-lives of 22 possible 2p radioactivity candidates, whose the 2p radioactivity released energy Q2p>0, obtained from the latest evaluated atomic mass table AME2016. The predicted results have good consistency with ones using other theoretical models such as the ELDM, GLDM and four-parameter empirical formula.

“…A and Z are the mass number and the charge number of the parent nucleus, respectively. χ 2 = 0.0143, which is determined by fitting the experimental half-lives of 19 Mg, 45 Fe, 48 Ni, and 54 Zn [37]. ν 0 is the assault frequency of the 2p pair on the barrier of the parent nucleus and estimated by the classical method…”

“…One case considers the two emitted protons from a parent nucleus are correlated strongly due to the proton-proton attraction. This decay process is called as " 2 He"cluster emission [27][28][29][30][31][32][33][34][35][36][37][38]. The other one refers to the completely uncorrelated emission, which is usually named as a three-body radioactivity [38][39][40][41][42][43][44][45][46][47][48][49][50].…”

“…On the other hand, many candidates of the 2p radioactivity were predicted by various models [28,[36][37][38][51][52][53][54]. As a matter of fact, the earliest determination for the candidates of the 2p radioactivity can date back to the pioneering work of Goldansky [6].…”

“…In calculations, to observe the model dependence of Q 2p values, the HFB29 [62] and KTUY [69] models will also be applied. In addition, for future measurements of the 2p radioactivity, based on our recent work on the 2p radioactivity [37], the half-lives of the 2p radioactivity will be calculated within the successful GLDM by inputting different kinds of Q 2p values. At last, the competition between 2p radioactivity and αdecay will be studied in the framework of the GLDM.…”

To search for new candidates of the true and simultaneous two-proton (2p) radioactivity, the 2p decay energies (Q2p) are extracted by the Weizsäcker-Skyrme-4 (WS4) model, the finite-range droplet model (FRDM), the Kourra-Tachibaba-Uno-Yamada (KTUY) model and the Hartree-Fock-Bogoliubov mean-field model with the BSk29 Skyrme interaction (HFB29). Then, the 2p radioactivity half-lives are calculated within the generalized liquid drop model (GLDM) by inputting the four types of Q2p values. By the energy and half-life constraints, it is found that the probable 2p decay candidates are the nuclei beyond the proton-drip line in the region of Z <50 or Z ≤ 50 based on each nuclear mass model. In the region beyond Z =50, the 2p-decaying candidates are predicted only using the HFB29 mass model. Finally, the competition between the true 2p radioactivity and α-decay for the nuclei above the N =Z =50 shell closures is discussed. It is shown that 101 Te, 111 Ba and 114 Ce prefer to 2p radioactivity and the dominant decay mode of 107 Xe and 116 Ce is α-decay.

Recent progress in two-proton radioactivity

During the last few decades, rare isotope beam facilities have provided unique data for studying the properties of nuclides located far from the beta-stability line. Such nuclei are often accompanied by exotic structures and radioactive modes, which represent the forefront of nuclear research. Among them, two-proton (2p) radioactivity is a rare decay mode found in a few highly proton-rich isotopes. The 2p decay lifetimes and properties of emitted protons hold invaluable information regarding the nuclear structures in the presence of a low-lying proton continuum; as such, they have attracted considerable research attention. In this review, we present some of the recent experimental and theoretical progress regarding the 2p decay, including technical innovations for measuring nucleonnucleon correlations and developments in the models that connect their structural aspects with their decay properties. This impressive progress should play a significant role in elucidating the mechanism of these exotic decays, probing the corresponding components inside nuclei, and providing deep insights into the open quantum nature of dripline systems.
