摘要

We looked at Xe-induced fusion reactions that resulted in the formation of the SHE Z=119. In this view, we considered four projectiles such as \(^{130}\) 130 Xe, \(^{132}\) 132 Xe, \(^{134}\) 134 Xe, and \(^{136}\) 136 Xe on \(^{157-159}\) 157 - 159 Tb. For the study of evaporation residue cross-sections, we investigated 12 fusion processes in total. Using an advanced statistical model, we assessed the probability of compound nucleus formation ( \(P_{CN}\) P CN ), survival probability( \(P_{Sur}\) P Sur ), and evaporation residue cross-sections ( \(\sigma _{EVR}\) σ EVR ). The measured ( \(P_{CN}\) P CN ) at optimal energy decreases as the mass number of projectile nuclei increases. In contrast, as the projectile-mass number increases, so does the likelihood of survival. For \(^{136}\) 136 Xe+ \(^{159}\) 159 Tb fusion reaction, the \(P_{Sur}\) P Sur and \(\sigma _{EVR}\) σ EVR are found higher value. When Xe-induced fusion events were considered, the expected cross-sections, which are in the order larger than femtobarn range, will serve as a roadmap for the synthesis of the SHE Z=119.
