Abstract
In this work we try to settle down the controversial predictions on the effect of doubly magic nuclei Sn and Pb on the mass distributions of fission fragments of super-heavy nuclei. For this we have calculated the mass distribution of super-heavy nuclei from Cn to 122 within the dynamical 4-dimensional Langevin approach. We have found that in "light" super-heavies the influence of Pb on the mass distributions is present but negligible small. In "heavy" super-heavies, Z=120-122, the (quasi)symmetric peaks and strongly asymmetric peaks at fragment mass close to =208 are of comparable magnitude.
