Query: Theoretical study of the synthesis of superheavy nuclei with Z= 119 and
  120 in heavy-ion reactions with trans-uranium targets   By using a newly developed di-nuclear system model with a dynamical potential
energy surface---the DNS-DyPES model, hot fusion reactions for synthesizing
superheavy nuclei (SHN) with the charge number Z = 112-120 are studied. The
calculated evaporation residue cross sections are in good agreement with
available data. In the reaction 50Ti+249Bk -> (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 with the mass asymmetry in the incident
channel increasing. The maximal ER cross sections for 58Fe+244Pu and 54Cr +
248Cm are relatively small (less than 0.01 pb) and those for 50Ti+249Cf and
50Ti+251Cf are about 0.05 and 0.25 pb, respectively.
