“…and i.s. Very recently, Seif et al [32] used the preformed cluster model (PCM) [33][34][35] to study the configurations of trans-lead isomers from Pb to U and their stability relative to g.s., and also examined their well-defined αdecay modes relative to the ground states. Gurvitz et al [36] introduced a Two Potential Approach (TPA) for αdecay by considering the total potential as the nuclear and Coulomb potential combination, and also the centrifugal potential contribution for unfavored decay.…”

The Modified Generalised Liquid Drop Model (MGLDM) is employed to analyze both the favored and unfavored α-decays in the ground states (g.s.) and isomeric states (i.s.) of some nuclei having proton numbers, 67 ≤ Z ≤ 106. The calculated half-lives closely match the experimental results, with a least standard deviation, 0.3598, which shows that the g.s. model ‘MGLDM’ can effectively be applied to the isomeric state decay. Royer's formula and Qian’s formula are employed in our calculations to determine the half-lives and the reported half-lives of the Two Potential Approach (TPA) and the GLDM are included, to compare the half-lives reproduced by MGLDM. The straight-line behavior of New Geiger-Nuttall (New G-N) plots for various isotopes for different kinds of transitions (g.s.→g.s., g.s.→i.s., i.s.→g.s., i.s.→i.s.) shows the New G-N law can be applied successfully in the isomeric state α-decays also.

In this work, considering the preformation factor of the emitted two protons in parent nucleus S2p \replaced{and the effect of the parent nucleus deformation}{}, based on the Wentzel-Kramers-Brillouin approximation and Bohr-Sommerfeld quantization condition, we \added{improve} a simple phenomenological model proposed by Bayrak [J. Phys. G: 47, 025102 (2020)] to systematically study the 2p radioactivity half-lives. \added{In this model, it contains two adjustable parameter V0 and aβ, which are related to the depth of nuclear potential obtained and the effect of deformation. } The calculated results show that this model can effectively reproduce the experimental data with a corresponding root-mean-square (RMS) standard deviation sigma = \replaced{0.683 }{0.700}. For comparison, the Gamow-like model (GLM) proposed by Liu et al. [Chin. Phys. C 45, 044110 (2021)], the generalized liquid drop model (GLDM) proposed by Cui et al. [Phys. Rev. C 101, 014301 (2020)], \replaced{effective liquid drop model (ELDM) proposed by M. Gonalves et al. [Phys. Lett. B 774, 14 (2017)], the two-potential approach with Skyrme-Hartree-Fock (TPASHF) proposed by Pan et al. [Chin. Phys. C 45, 124104 (2021)], the phenomenological model with a screened electrostatic barrier (SEB) propoesed by Zou et al. [Chin. Phys. C 45, 104101 (2021)], the unified fission model (UFM) proposed by Xing et al. [Chin. Phys. C 45, 124105 (2021)] ,the Coulomb and proximity potential model for deformed nuclei (CPPMDN) proposed by Santhosh [Phys. Rev. C \textbf{104}, 064613 (2021)],}{} a two-parameter empirical formula proposed by Liu \emph{et\ al}. [Chin. Phys. C \textbf{45}, 024108 (2021)], and a four-parameter empirical formula proposed by Sreeja et al. [Eur. Phys. J. A \textbf{55}, 33 (2019)] are also used. In addition, we use this model to predict the 2p radioactive half-lives of some possible potential nuclei whose 2p radioactivity are energetically allowed or observed but not yet quantified in NUBASE2020.
