We calculate the neutron-evaporation residue cross sections σ 3n , σ 4n , and σ 5n in the hot-fusion reactions 48 Ca+ 242,244 Pu→ 290,292 114 * over a wide range of compound-nucleus excitation energies (E * CN = 34-53 MeV). We work with the dynamical cluster-decay model (DCM), with a single parameter, the neck-length parameter R. To calculate neutron-evaporation cross sections, we choose the superheavy proton magic Z = 126 and neutron magic N = 184. Among the 3n, 4n, and 5n production cross sections for 290,292 114 * , only the 3n decay cross sections of 292 114 * correspond to spherical fragmentation. The 4n and 5n cross sections of 292 114 * and 3n, 4n, and 5n cross sections of 290 114 * could only be fitted after the inclusion of quadrupole deformations β 2i within the optimum orientation approach. Changes in the angular momentum and N/Z ratio do not significantly influence the fragmentation paths of 290,292 114 * superheavy nuclei. Larger barrier modification is required for the lower angular momentum states and lighter neutron clusters. The contribution of the fusion-fission component is also computed for the compound nucleus 292 114 * in the energy range E * CN = 27-47 MeV.

“…Extensive theoretical and experimental search for cluster emission from various heavy and super-heavy nuclei ranging from 14 C to 80 Ge [46][47][48][49] have been studied. The present study focus on the cluster decay such as 4 He, 22 Ne, 26 Mg, 28,30 Si, 34 S, 40 Ca and 46 Ca which are magic nuclei or near the magic nuclei whose half-lives are maximum.…”

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.
