Description

We investigated Coulomb cross-sections (σCA) 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 64Ni + 238U the Coulomb cross-sections are higher and for the fusion reaction of 50Ti + 249Cf the Coulomb cross-sections smaller. Coulomb fission time scales were discovered to be less for 58 Fe particles. The Coulomb fission cross-sections were investigated at optimal energy. Coulomb fission cross-sections were also anticipated and compared to fusion σf)u and evaporation residue cross-sections σER. The predicted Coulomb fission and fusion cross-sections are of the order of milli barn and evaporation residue cross-sections σER are of the order of femto barns. 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. (author)
