Investigation of decay modes of superheavy nuclei

A detailed investigation of different decay modes, namely alpha decay, beta decay, cluster decay, including heavy particle emission ( $$Z_{c}>28$$ ), and spontaneous fission, was carried out, leading to the identification of new cluster and beta-plus emitters in superheavy nuclei with $$104 \le Z \le 126$$ . For the first time, we identified around 20 beta-plus emitters in superheavy nuclei. Heavy-particle radioactivity was observed in superheavy elements of atomic number in the range $$116\le Z \le 126$$ . $$^{292-293}$$ Og were identified as $$^{86}$$ Kr emitters, and $$^{298}122$$ and $$^{300}122$$ were identified as $$^{94}$$ Zr emitters, whereas heavy-particle radioactivity from $$^{91}$$ Y was also observed in $$^{299}123$$ . Furthermore, the nuclei $$^{300}124$$ and $$^{306}126$$ exhibit $$^{96}$$ Mo radioactivity. The reported regions of beta-plus and heavy-particle radioactivity for superheavy nuclei are stronger than those for alpha decay. The identified decay modes for superheavy nuclei are presented in a chart. This study is intended to serve as a reference for identifying possible decay modes in the superheavy region.
