Damped collisions of tranactinide nuclei (238U+238U, 232Th + 250Cf, and 238U+ 248Cm) have been studied within the realistic model based on solution of multidimensional transport equations. Large charge and mass transfer was found in these reactions due to the inverse (anti-symmetrizing) quasi-fission process leading to formation of survived superheavy long-lived neutron-rich nuclei, suitable for subsequent chemical analysis. In many events lifetime of the composite system consisting of two
