This investigation aims to find an appropriate dinuclear system for the formation of ${}^{296}$119 superheavy compound nucleus. By studying the driving potential and measuring the capture cross section of the reactions, the evolution of the dinuclear system can be understood. In this study, we obtained capture, fusion, and evaporation residue cross sections and survival probability at energies near the Coulomb barrier for four reactions, namely $^{45}$Sc + $^{251}$Cf, $^{42}$Ca + $^{254}$Es, $^{39}$K + $^{257}$Fm, and $^{38}$Ar + $^{258}$Md. Our calculations show that the reaction $^{38}$Ar + $^{258}$Md is a suitable choice for the formation of an element with 119 protons among the studied reactions from a theoretical viewpoint.

聚变反应中296 119超重复合核的双核系统研究

本研究旨在为${}^{296}$119超重复合核的形成寻找合适的双核系统。通过研究驱动电位和测量反应的捕获截面,可以了解双核系统的演变。在本研究中,我们获得了四种反应(即$^{45}$Sc + $^{251}$Cf、$^{42}$Ca + $^{254}$Es、$^{39}$K + $^{257}$Fm 和$^{38}$Ar + $^{258}$Md)在库仑势垒附近能量下的捕获、融合和蒸发残留物横截面和存活概率。我们的计算表明,从理论角度来看,$^{38}$Ar + $^{258}$Md反应是在所研究的反应中形成具有 119 个质子的元素的合适选择。
