摘要：

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 (46Ti, 3n) 297121 and 252 Es (46Ti,3n) 295121 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.
