| Abstract: | The survival probability of super heavy nuclei produced in cold fusion reactions is studied by using the standard Fermi gas level density formula and analyzed with fission and neutron evaporation characteristics predicted in different theoretical models. The level density formula used in this letter suppresses the ratio ofneutron emission width to fission width, Γn/Γf. Thedependence of Γn/Γf on the saddle point leveldensity parameter and excitation energy is also investigated. |
