Fusion-Fission and Quasifission Lifetimes of Fusion Reactions Strived to Synthesize the SHE Z=120

Abstract

It is generally known that the production of SHE is hampered by the quasifission (QF) and fusion-fission (FF) lifetimes. So, utilizing nucleus-nucleus potential, we looked into the quasifission durations and fusion-fission lifetimes of seven fusion reactions. For the fusion process of \(^{58}\)Fe+\(^{244}\)Pu, the quasifission and fusion-fission lifetimes of 8.4 zs and 92.4 as, respectively, are found to be longer. The optimal energies at which maximum cross-sections of fusion, quasifission, fusion-fission, and evaporation residue exist have been reported. The fusion reactions of \(^{51}\)V+\(^{249}\)Bk show a greater evaporation residue cross-section, whereas \(^{55}\)Mn+\(^{243}\)Am show a smaller cross-section. Therefore, thorough research as well as optimal energies, quasifission lifetimes, and fusion-fission lifetimes provide insight into the formation of SHE Z=120.
