Description

Using the experimental evaporation residue cross sections in the 48Ca-induced complete fusion reactions and the complete fusion cross sections calculated within the dinuclear system model, the survival probabilities of superheavy nuclei with charge numbers Z=112-116 and 118 in the xn-evaporation channels are extracted. The effects of angular momentum and deformations of colliding nuclei are taken into account. The obtained dependence of the survival probability on Z indicates the next doubly magic nucleus beyond 208Pb at Z≥120.
