A Study on the Synthesis of Superheavy Element Z = 125

We have studied the α-decay chains of superheavy nuclei Z = 125 in the range 265 ≤ A ≤ 336. The nuclei 303–315125 were found to have long half-lives and hence could be sufficient to detect them 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). The selected most probable projectile-target combinations to synthesize superheavy nuclei 303–315125 are Co+Cf, Ni+Bk, and Cu+Cm. We hope that our predictions may be guide for the future experiments in the synthesis of the new superheavy element Z = 125.
