“…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.…”

“…From the figure it is observed that as the mass number of cluster increases scattering potential also increases. The studied scattering potential of 6 Li, 9 Be, 22 Ne, 26 Mg, 28,30 Si, 34 S, and 40,46 Ca in the isotope of superheavy element 299 122 with the variant of separation distance between the two nuclei is presented in Figure 2. From the figure it has been examined that the driving potential for 299 122 varies between 80MeV to 184MeV during the cluster emission of 22 Ne and 46 Ca respectively.…”

“…The half-life values of Prox 13 compared with the different models such as Univ [1], NRDX [2], UDL [3] and Horoi [4] Figures 4 shows the variation of logarithmic half-lives of Prox 13 and different models such as Univ, NRDX, UDL Horoi with the mass number of clusters. The half-lives of the cluster emission of 4 He, 6 Li, 9 Be, 22 Ne, 26 Mg, 28,30 Si, 34 S, and 40,46 Ca are calculated for the super-heavy nuclei [299][300][301][302][303][304][305][306] 122. Among all the studied clusters, alpha decay has minimum half-lives.…”

“…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.…”

“…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. The hypothetical super-heavy nuclei such as Z=120, 122 124 and 126 are most predictable super-heavy nuclei in the island of stability.…”

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.

Decay of dinuclear systems formed from dubnium

et al. 2021

View full text Add to dashboard Cite

The radioactivity of the superheavy nuclei 250−275 Db is studied and presented using the Coulomb and proximity potentials. The half-lives corresponding to different decay modes such as α, cluster decay ( 12 C, 14 N, 18,20 O, 23 F, 20 Ne, 34 S, 28 Mg and 40 Ca) and spontaneous fission in the superheavy nuclei 250−275 Db are studied. The studied half-lives are compared with the available experiments. The decay modes and the branching ratios of isotopes of dubnium are presented. The isotopes of dubnium, 254−263 Db, are identified as α emitters, whereas isotopes such as 250−253 Db and 264−275 Db are identified as having spontaneous fission. The identified alpha emitting isotopes of dubnium have decay energies from 6 MeV to 10 MeV and half-lives 1 ms to 100 s. The possible projectile-target combinations to synthesise the superheavy nuclei 253−263 Db were predicted. The fusion of spherical projectile and target yields larger evaporation residue cross-sections.
