Abstract

IIn this research spontaneous fission of 284Fl superheavy nucleus has been studied using Coulomb and nuclear proximity potential. Released energy in each fragmentation Q, driving potential (V-Q), penetrability, decay constant and fission yield for each individual fragmentation are calculated. With respect to the mass and charge asymmetry, the most favorable fragmentation in the binary spontaneous fission occurs for the highest Q value and the lowest driving potential (V-Q). For spontaneous fission of 284Fl superheavy nucleus, the highest yield has been seen for 136Xe isotope (N = 82, Z = 54) as one of the Fragments. The comparison between relative yields shows the role of doubly magic and near doubly magic nuclei in having the highest fission yield. The spontaneous fission half-life of 284Fl superheavy nucleus are calculated by obtaining the total decay constant λ and compared with the results of semi empirical formula as well as experimental data. Satisfactory agreement achieved between the results of this approach and experimental data than the results of semi empirical formulas
