Investigation on Xenon-Induced Fusion Reaction to Synthesize Superheavy Element (SHE) Z=119
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 \(^{130}\)Xe, \(^{132}\)Xe, \(^{134}\)Xe, and \(^{136}\)Xe on \(^{157-159}\)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 (\(P_{CN}\)), survival probability(\(P_{Sur}\)), and evaporation residue cross-sections (\(\sigma _{EVR}\)). The measured (\(P_{CN}\)) 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 \(^{136}\)Xe+\(^{159}\)Tb fusion reaction, the \(P_{Sur}\) and \(\sigma _{EVR}\) 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.
期刊介绍:
The Brazilian Journal of Physics is a peer-reviewed international journal published by the Brazilian Physical Society (SBF). The journal publishes new and original research results from all areas of physics, obtained in Brazil and from anywhere else in the world. Contents include theoretical, practical and experimental papers as well as high-quality review papers. Submissions should follow the generally accepted structure for journal articles with basic elements: title, abstract, introduction, results, conclusions, and references.
