Studies on the synthesis of superheavy element Z = 123

Abstract

We have studied the α-decay chains of superheavy nuclei Z = 123 in the range 265 ≤ A ≤ 316. The nuclei 303–308123 were found to have longer half-lives and hence could be detected 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) of different projectile–target combinations to synthesize superheavy element Z = 123. The selected most probable projectile–target combination to synthesize superheavy nuclei with Z = 123 is Mn + Cf. We hope that our predictions may be guide for the future experiments in the synthesis of new superheavy element Z = 123.
