Abstract:

We discuss a hardship in synthesis of heaviest super heavy elements in massivenuclei reactions due to the hindrance to complete fusion of reacting nucleicaused on the onset of quasifission process which strongly competes withcomplete fusion and due to the strong increase of fission yields along thede-excitation cascade of the compound nucleus in comparison with theevaporation residue formation. The hindrance to formation of compound nucleusand  evaporation  residue is determined by the characteristicof the entrance channel.

Key words: Capture, Quasifission, Complete fusion, Fast fission, Fusion-fission, Evaporation residue
