Abstract

Abstract: The production cross sections for the synthesis of superheavy elements 284–292 Fl ( Z = 114) using the fusion reactions 48 Ca+ 236-244 Pu were systematically calculated. Using Coulomb and proximity potentials as the interaction barrier, we calculated the capture cross section, probability of CN formation, survival probability of excited compound nuclei, fusion cross section, and evaporation residue (ER) cross section for these reactions at energies near and above the Coulomb barrier. Our calculated ER cross section values for the reactions 48 Ca+ 240 Pu→ 288 Fl, 48 Ca+ 242 Pu→ 290 Fl and 48 Ca+ 244 Pu→ 292 Fl are in excellent agreement with available experimental values. The predicted maximum value of the ER cross section in 2n, 3n, 4n, and 5n channels for all the reactions 48 Ca+ 236–244 Pu→ 284–292 Fl are listed. It was found that the reactions 48 Ca + 243 Pu→ 291 Fl and 48 Ca + 244 Pu→ 292 Fl were more favorable with a maximum ER cross section of 6.924 (3n) and 9.033 pb (4n), respectively. Our studies will be useful for future experiments to synthesize the isotopes of element Fl that have not been synthesized so far.
