摘要：
Using the statistical model and the fission and the neutron evaporation characteristics predicted in different theoretical models, we analyze the survival probabilities of superheavy nuclei produced in Pb-208-based cold fusion reactions. For Z<114 all models give similar ratios of the neutron evaporation to the fission width. But for Z<greater than or equal to>114, they yield different results for this ratio and therefore lead to different evaporation residue cross sections.
