On Isotope Dependence of Superheavy Nucleus Production

    Graphical Abstract
    • Abstract
  • The cross sections of the compound nucleus formation and e vaporation residue for the 54Fe+204Pb， 56Fe+206Pb， 58Fe+208Pb cold fusion and 32,34, 36S+238U hot fusion have been calculated by using a twoparameter Smoluchowski equation. Our results clearly show the isotope dependence of superheavy nucleus production. The formation cross sections of the neutronrich isotope are， generally speaking， obviously enhanced due to the lower Coloumb barrier ， lower height of the conditional saddlepoint， and smaller neutron separation energy.
