Abstract

We have predicted possible isotopes for Z = 116 by studying the competition between different decay modes such as binary, ternary, cluster radioactivity, and alpha decay. The spontaneous fission is a dominant decay mode for 274-276Lv and 295-339Lv; alpha decay is a prominent decay mode for the nuclei 277-294Lv. In the second part, we have identified the most possible projectile-target combinations to synthesize the superheavy nuclei with Z = 116. We have also identified the most suitable projectile-target combinations to form compound nucleus with Z = 116 which are 36Ar + 248Cf, 36Ar + 249Cf, 36Ar + 250Cf, 36Ar + 251Cf, 36Ar + 252Cf, 36Ar + 253Cf, 37Ar + 253Cf, 38Ar + 253Cf, 39Ar + 253Cf, 40K + 253Bk and, 40K + 254Bk. We also identified the most probable spontaneous fission fragments after alpha decay chains of 284-294Lv.
