In the reactions with heavy ions leading to superheavy nuclei the formation of a compound nucleus is suppressed strongly by competing quasifission process and deep inelastic collisions. Moreover, the excited compound nucleus formed in fusion reactions mainly undergoes fission. The study of fission of heavy and superheavy nuclei gives important information about compound nucleus formation cross sections, fission barriers and survival probabilities of these nuclei. The main recent results of the experimental studies of the compound nucleus fission and quasifission processes in the heavy-ion-induced reactions leading to the formation of nuclei with Z ≥ 102 are discussed. The most attention is paid to the experimental investigations of mass-energy distributions of reaction products measured using the CORSET spectrometer.
