Abstract

We have studied the α-decay properties of superheavy nuclei Z=121 in the range 265A316. A detailed study of competition between α decay and fission enables us to identify the possible isotopes for superheavy element Z=121. The nuclei 121299304 were found to have long half-lives and hence they could be detected if synthesized in a laboratory. After identifying the possible isotopes, we have identified the most probable projectile-target combinations by studying the fusion cross section, evaporation residue cross section, compound nucleus formation probability (PCN), and survival probability (PSurv) of different projectile-target combinations to synthesize the superheavy element Z=121. The most probable projectile-target combinations to synthesize the superheavy nuclei 121299305 is V+Cf. The predicted α-decay half-lives and projectile-target combinations play a vital role in the synthesis of the superheavy element Z=121.
