摘要：
We have studied the alpha-decay properties of superheavy nuclei Z = 121 in the range 265 <= A <= 316. A detailed study of competition between alpha decay and fission enables us to identify the possible isotopes for superheavy element Z = 121. The nuclei (299-304) 121 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 (P-CN), and survival probability (P-surv ) of different projectile-target combinations to synthesize the superheavy element Z = 121. The most probable projectile-target combinations to synthesize the superheavy nuclei (299-305)121 is V + Cf. The predicted alpha-decay half-lives and projectile-target combinations play a vital role in the synthesis of the superheavy element Z = 121.
