“…The amount of energy released from the cluster decay such as 4 He, 6 Li, 9 Be, 12 C, 14 N, 20,22 Ne, 23 N, [24][25][26] Mg, [28][29][30] Si, 31 P, [32][33][34] S, 35 Cl, 36,38,40 Ar, and [40][41][42][43][44][45][46] Ca are studied using mass excess values available in the reference [54]. The Figure 1 shows the variation of scattering potential with the mass number of clusters.…”

“…Earlier workers [27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44] studied different decay modes such as spontaneous fission, ternary fission, cluster decay and alpha decay in the heavy and super-heavy region and also predicted suitable projectile-target combinations to synthesize these super-heavy nuclei. Karpeshin [45] has shown that the choice of a specific shape of the proximity potential affects not only the shape of the barrier, but can also change the total kinetic energy of fragments by tens of MeV.…”

Cluster radioactivity is an intermediate between alpha decay and spontaneous fission. It is also an exotic decay obtained in superheavy nuclei. When a cluster decay is detected in superheavy nuclei, the daughter nuclei is having near or equal to doubly magic nuclei. We have investigated cluster decay of isotopes of He, Li, Be, Ne, N, Mg, Si, P, S, Cl, Ar and Ca in the superhaevy nuclei region 299-306122. We have also compared the logarithmic half-lives of cluster decay with that of other models such as Univ [1], NRDX [2], UDL [3] and Horoi [4]. From this study it is concluded that cluster decay of 4He, 22Ne, 26Mg, 28Si 30Si, 34S, 40Ca and 46Ca are having shorter logarithmic half-lives compared to exotic cluster decay modes.

“…Recently, theoretical investigation of the physical laws governing the stability of superheavy nuclei (SHN) against α-decay and/or fission has become an emerging area of research [1][2][3][4][5][6][7][8]. α-decay, being the dominant mode of decay, is proved to be significant in the identification of new SHN while the spontaneous fission (SF) hardly helps in this regard for its tendency to abort the α-decay chains prior to the synthesis of new nuclei in the expected regime of the nuclear chart [9][10][11][12][13][14][15] (see [16] references therein).…”

α-decay half-lives ( T 1 / 2 α -values) of even–even and superheavy nuclei (SHN) are determined employing interaction potential involving Coulomb and proximity potentials. The obtained results are compared with the experimental ones and to assess the precision of the present model in reproducing the experimental half-lives, a comparison is drawn with the other methods as well. We require disintegration energy (Q α -values) as an input in order to predict the ( T 1 / 2 α -values) of an experimentally unknown SHN. So, utilizing periodic-orbit theory within microscopic-macroscopic formalism, we have calculated the binding energies and thereafter, Q α -values of known SHN. The results are found to be in good agreement with the experimental ones. Subsequently, we predict the logarithmic values of T 1 / 2 α ’s for even–even unknown SHN whose atomic numbers lie in 118 ⩽ Z ⩽ 126 regime and compare our results with those calculated employing other theoretical methods. Also, the study of spontaneous fission half-lives and branching ratios leads us to predict the SHN which can be identified through α-decay chains in the laboratories. We believe that this work can play a significant role in the experiments leading to the synthesis and identification of new superheavy elements.

“…It is also evident from the literature that mass asymmetry in fission due to the fragmentation during the formation of superheavy nuclei [16]. The different decay modes such as /cluster-decay, heavy particle radioactivity and spontaneous fission half-lives are dominant in the heavy and superheavy region [17][18][19][20][21][22][23][24][25][26][27][28][29][30]. The main decay mode depends on the binding energy and type of fragmentation structure connected with them.…”
