“…The possibility of the heavy particle radioactivity (cluster decay) was also predicted in the heavy and superheavy nuclei [57][58][59][60][61]. Discussion of cluster decay started by Sandulescu et al in 1980 [62] and firstly observed by Rose and Jones [63].…”

A comprehensive study of favoured and unfavoured α-decay, cluster decay, weak-decay along with spontaneous fission in undetected superheavy nuclei within the range for proton number 111≤Z≤118 and neutron number 161≤N≤192 is performed. Half-lives for various mentioned decays are estimated with good accuracy on the basis of NUBASE2020 and are found in excellent match with the known half-lives. α-decay mode is found most probable in this wide range and correspondingly potential α-decay chains are reckoned. Peculiarly, the chances of cluster emission, as well as weak-decay, are also anticipated in this region of the periodic chart which open new pathways of detection of superheavy nuclei.

The possibility of cluster emission from trans-lead (86≤Z≤96) region of periodic chart has been explored comprehensively by employing few empirical formulas which are modified by adding angular momentum (l) or isospin-dependent (I = (N − Z)/A) or both terms for the calculation of cluster decay half-lives. These modified versions of the formulas are found with lesser χ 2 per degree of freedom and root mean-square error, in addition to the smaller values of some other statistical parameters, while compared to their corresponding old versions on available 61 experimental data of cluster radioactivity. By applying the modified version of the formula given by Balasubramaniam et al. [PRC 70 (2004) 017301], the most accurate formula among these, half-lives of several clusters i.e. isotopes of Be, B, C, N, O, F, Ne, Na, Mg, and Si are predicted systematically for the several isotopes in the trans-lead region. The contest of cluster emission with α-decay has been investigated in form of branching ratio which brings several potential cluster emissions into the probable decay modes of these nuclei. The accurate prediction of half-lives of such clusters is expected to be crucial for the future experimental observations where α-decay is observed dominantly.

“…Since then, on the basis of the quantum picture of α-decay, many models have been developed to calculate the half-lives. Cluster model [21][22][23], Two potential approach [24], Unified model for α decay and α capture [25,26], Generalized liquid drop model (GLDM) [27][28][29][30], Modified generalized liquid drop model (MGLDM) [31][32][33][34][35][36], Effective liquid drop model (ELDM) [37], Coulomb and proximity potential model (CPPM) [38][39][40] are some of them which could reproduce the data very near to experimental values.…”

“…We would like to point out that we can reasonably simulate the observed α-decay half-lives of superheavy nuclei using our model. Also, the research has been already made on cluster decay, α-decay and 2αdecay in heavy and superheavy regions [31][32][33][34][35][36] which results in lower standard deviation. Hence it is a new enhanced mechanism to study the decay of heavy and superheavy elements.…”

The α-decay half-lives for the isotopes of nuclei W, Re, Os, Ir and Pt in the range 157≤A≤193, have been studied by using the Modified Generalised Liquid Drop Model (MGLDM). The half-lives predicted for some even-even nuclei by using the deformed Two Potential Approach (TPA) [Comm. Theo. Phys. 74, 055301 (2022)] are considered and included for the comparison. Additionally, we have analysed the α-decay half-lives using seven ℓ-dependent empirical formulae, and compared the results with the experimental data. The standard deviation and the average deviation for log10T1/2 by using MGLDM is obtained as 0.6025 and 0.5403, respectively. Also, the results of MGLDM match well with predictions of TPA, with standard deviation of 0.47 and 0.44 respectively. A dip in the half-life curve or a peak in the decay energy curve at 82, a magic neutron number of the daughter nuclei of W74158 increases the viability of the calculations. Also, the linear nature of Geiger-Nuttall law, Universal law, the relation connecting log10T1/2 and ZQα-1/2, and the New Geiger-Nuttall law helps to calculate the half-lives of newly synthesized and unknown isotopes, making MGLDM more reliable.
