“…From these two figures, we can find the minimum logarithmic half-life of the double magic kernel (Z=82, N=126). Consequently, this confirms that neutron shell closure plays a crucial role in cluster radioactivity [68,71,72]. We hope that these predicted half-lives will be useful for identifying new cluster emissions of the trans-tin region in future measurements.…”

“…As is well known, cluster radioactivity is closely related to the shell effect, which has prompted widespread [68,71,72]. To verify the shell effect in the cluster radioactivity process, we calculate the cluster radioactivity half-lives of the emitter cluster from isotopes and from isotopes, which give the daughters and .…”

In this study, considering the modified preformation probability to be , where and are the α-particle preformation probability and an adjustable parameter proposed by Wang et al. [Chin. Phys. C 45, 044111 (2021)], respectively, we extend a new simple model put forward by Bayrak [J. Phys. G 47, 025102 (2020)] to systematically study the cluster radioactivity half-lives of 28 trans-lead nuclei ranging from to , which is based on the Wentzel-Kramers-Brillouin approximation and Bohr–Sommerfeld quantization condition. For comparison, a universal decay law proposed by Qi et al. [Phys. Rev. C 80, 044326 (2009)], a three-parameter model-independent formula put forward by Balasubramaniam et al. [Phys. Rev. C 70, 017301 (2004)], and the semi-empirical model proposed by Tavares et al. [Eur. Phys. J. A 49, 1 (2013)] are used. Our calculated results reproduce the experimental data well, with a standard deviation of 0.818. Furthermore, we use this model to predict the cluster radioactivity half-lives of 51 possible cluster radioactive candidates whose cluster radioactivities are energetically allowed or observed but not yet quantified in NUBASE2020.

“…To calculate the logarithmic half-lives of cluster emission, there are various available empirical formulas viz. Royer formula [101], the formula given by Balasubramaniam et al (BKAG) [102], Horoi formula [103], the formula by Ren et al [30], NRDX formula [104], universal decay law (UDL) [74], universal curve formula (UNIV) [105], Tavares-Medeiros formula (TM) [106], formula by Soylu [107], improved unified formula (IUF) [97], improved semi-empirical formula (ISEF) [98] and some recent modified formulas [108]. Considering the absence of experimental data of cluster radioactivity in superheavy region, only UDL formula among the above mentioned formulas demonstrates for the existence of a competitive relationship between α-decay and cluster radioactivity in superheavy region, due to its treatment as both the preformation model and the fission-like mechanisms [109], and henceforth justifies its use for further predictions.…”

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.
