| 英文摘要 | By using a newly developed dinuclear system model with a dynamical potential energy surface-the DNS-DyPES model-hot fusion reactions for synthesizing superheavy nuclei (SHN) with charge numbers Z = 112-120 are studied. The calculated evaporation residue cross sections are in good agreement with available data. In the reaction Ti-50 + Bk-249. -> (299-x)119 + xn, the maximal evaporation-residue (ER) cross section is found to be about 0.11 pb for the 4n-emission channel. For projectile-target combinations producing SHN with Z = 120, the ER cross section increases as the mass asymmetry in the incident channel increases. The maximal ER cross sections for Fe-58 + Pu-244 and Cr-54 + Cm-248 are relatively small (less than 0.01 pb) and those for Ti-50 + Cf-249 and Ti-50 + Cf-251 are about 0.05 and 0.25 pb, respectively. |
