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 (P_CN) and survival probability (P_Surv) 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.

Z = 123的超重元素的合成研究

我们研究了α超重核衰变链ž  = 123在265≤范围 甲 细胞核≤316 ^303-308 123中发现有较长的半衰期，因此如果在一个实验室中合成的，可检测它们。在确定了可能的同位素之后，我们通过研究不同弹丸-目标组合物的融合截面，蒸发残留物截面，复合核形成概率（P _CN）和生存概率（P _Surv），确定了最可能的弹丸-目标组合。合成超重元素Z =123。用于合成Z  = 123的超重核的最可能的弹丸-目标组合为Mn +Cf。我们希望我们的预测可以为将来合成新的超重元素Z  = 123的实验提供指导。
