Abstract：
The excitation function of evaporation residues formation probability of three heavy nuclei 194Pb, 200Pb and 206Pb is calculated using Langevin equation coupled with a statistical decay model. The results show that the ratio of neutron-to-proton (N/Z) of compound nuclei has an effect on survival probability and that a higher N/Z leads to a larger survival probability. This is due to the dependence of the fission barrier and pre-saddle particle emission on the N/Z of the systems.
