The peculiarities of the production and decay of superheavy nuclei
The interest in the study of the fission process of superheavy nuclei mainly deals with the opportunity to obtain information about the cross-section of the compound nucleus (CN) formation at excitation energies E^*~15-30 MeV. It allows one to estimate the survival probability of the superheavy composite system after evaporation of 13 neutrons, i.e. in ''cold'' or ''warm'' fusion reactions. However, in order to solve this problem deeper understanding of the coalescence processes between colliding nuclei, the competition between fusion-fission and quasi-fission processes is needed. The characteristics of both processes, their manifestation in the experimental observables and the relative contribution to the capture cross-section in dependence on the excitation energies, reaction entrance channel etc were investigated for a wide range of target-projectile combinations. Results of the experiments devoted to the study of the fusion-fission and quasi-fission processes in the reactions of the formation of the superheavy nuclei with Z=102-122 are presented. The heavy ions ^26Mg, ^48Ca, ^50Ti, ^58Fe and ^64Ni were used as projectiles.
