摘要

We investigate the dependences of the potential energy surfaces(PES)and the fusion probabilities for some cold fusion reactions leading to super-heavy elements on the nuclear shell effect and pairing energy.It is found that the shell effect plays an important role in the fusion of the super-heavy element while pairing energy's contribution is insignificant.The fusion probabilities and evaporation residue cross sections as functions of the Ge-isotope projectile bombarding 208 Pb are also investigated.It is found that evaporation residue cross sections do not always increase with the increasing neutron number of Ge-isotope.
