Abstract
Based on the dinuclear system model, the calculated evaporation residue cross sections matched well with the current experimental results. The synthesis of superheavy elements \(Z=121\) was systematically studied through combinations of stable projectiles with \(Z = 21\)–30 and targets with half-lives exceeding 50 d. The influence of mass asymmetry and isotopic dependence on the projectile and target nuclei was investigated in detail. The reactions \(^{254}\)Es (\(^{46}\)Ti, 3n) \(^{297}121\) and \(^{252}\)Es (\(^{46}\)Ti, 3n) \(^{295}121\) were found to be experimentally feasible for synthesizing superheavy element \(Z = 121\), with maximal evaporation residue cross sections of 6.619 and 4.123 fb at 219.9 and 223.9 MeV, respectively.
