Abstract
We investigate the cold fission/fusion paths of superheavy nuclei within the two-center shell model, in order to find the best projectile-target combinations of their production. The fission/fusion yields are estimated by using the semiclassical approach. We predict several asymmetric combinations of relative long-living fragments, which can be used in fusion experiments of superheavy nuclei with Z > 118.
