Abstract:The survival probability of super heavy nuclei produced in cold fusion reactions is studied by using thestandard Fermi gas level density formula and analyzed with fission and neutron evaporation characteristics predicted indifferent theoretical models. The level density formula used in this letter suppresses the ratio of neutron emission widthalso investigated.
Keywords:super-heavy nuclei   survive probability   fission width   neutron emission width
