Coulomb Fission and Coulomb Time Scales of Superheavy Nuclei Z = 120
We investigated Coulomb cross-sections ( σ A Cf ) and time scales for seven fusion reactions which were attempted to synthesize superheavy element Z = 120. A simple extended trapezoidal integration method was used to assess the Coulomb fission cross-sections. For the fusion reaction of 64 Ni + 238...

are of the order of femtobarns. The comprehensive examination of the cross-sections and lifetimes of the Coulomb fission provides a possible explanation for the failure of the synthesis of super heavy nuclei Z = 120. As a result, additional research is necessary in order to validate the anticipated Coulomb fission cross-sections and time-scales. |
