It is important to study the different decay modes of superheavy nuclei such as spontaneous fission, ternary fission and cluster decay. We studied the spontaneous fission, ternary fission and cluster decay of predicted isotopes of superheavy nuclei [Formula: see text] and compared with that of alpha decay. This enables us to study the competition between spontaneous fission, ternary fission, cluster decay and alpha decay in the superheavy nuclei [Formula: see text]. We have studied the half-lives and decay constants of different decay modes. We have also studied the branching ratio of alpha decay with respect to other decay modes. This study reveals that alpha decay is the most dominant decay mode for the superheavy nuclei [Formula: see text] and hence these nuclei can be detected through the alpha decay mode only.

In this work, we have made an attempt to study the cluster-decay half-lives and alpha-decay half-lives of the superheavy nuclei [Formula: see text]Og by considering the temperature-dependent (TD) and also temperature-independent (TID) proximity potential model. The evaluated half-lives were compared with that of the experiments. To predict the decay modes, we have compared the cluster-decay half-lives and alpha-decay half-lives with that of spontaneous fission half-lives. This work also predicts the decay chains of the superheavy nuclei [Formula: see text]Og and finds an importance in the synthesis of further isotopes of superheavy element Oganesson.

We considered the systematics of Alpha-decay (AD) half-life (HL) of super-heavy nuclei (SHN) versus the decay energy and the total [Formula: see text]-kinetic energy. We have considered a potential model with Yukawa proximity potential and thereby calculated the HLs. Our results compared with experimental data and the empirical estimates. Also, we obtained [Formula: see text]-preformation factors from the ratio between theoretical and experimental results for a few super heavy nuclei. The results indicate the acceptability of the approach.

Cluster radioactivity is a rare cold nuclear process which is intermediate between alpha decay and spontaneous fission. The present work is a theoretical investigation of the feasibility of alpha decay and cluster radioactivity from proton rich Osmium (Os) isotopes with mass number ranging from 162–190. Osmium forms a part of the transition region between highly deformed and spherical nuclei. Calculations have been done using unified fission model and Hartree–Fock–Bogoliubov (HFB) theory. We have chosen only those decays with half-lives falling in measurable range. Geiger–Nuttall plot has been successfully reproduced. The isotope which is most favorable to each decay mode has a magic daughter nucleus.
