“…It is worth mentioning that the New Geiger-Nuttall (New G-N) plot was initially proposed by Chen et al [61] for one proton radioactivity and, was subsequently adapted by Liu et al [62] to accommodate two proton radioactivity. Recently we [51,52] have employed the New G-N plot in ground state α-radioactivity for the first time. And, now the linearity of the New G-N plot shows how effectively it can be applied in i.s.…”

“…The works using MGLDM [46][47][48][49][50] could well explain the cluster decay, α-decay, and 2α-decay in heavy and superheavy regions. Modified Generalized Liquid Drop Model (MGLDM) was proposed to study the ground state decays of the nuclei in the superheavy region [46], and later it was applied in the ground states of the heavy region [51,52] also and successfully regenerated the experimental results. Here we are applying the MGLDM in the isomeric states for the first time.…”

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.
