The production cross section of various isotopes of Og superheavy nucleus through cold reactions of 84Kr+208Pb, 86Kr+208Pb and 88Kr+208Pb is calculated based on the di-nuclear system (DNS) model using double-folding and proximity potentials. Due to the lack of experimental data, two 70Zn+208Pb and 70Zn+209Bi reactions are studied also for comparison. The calculated formation cross sections of Og, SHN using two potentials are compared with each other as well as experimental data. The exact Ginzburg–Landau (EGL) theory is applied in order to obtain the temperature of produced 292Og, 294Og, 296Og, 278Nh and 277Cn superheavy isotopes. Analyzing of entire calculated results revealed that the obtained formation cross sections using double-folding potential are consistent with the available experimental data compared with the results of proximity potential.
