Abstract: The dynamics of transfer reactions in collisions of two very heavy nuclei$^{238}$U+$^{238}$U is studied within the dinuclear system DNS model.Collisions of two actinide nuclei form a super heavy composite system during avery short time, in which a large number of charge and mass transfers may takeplace. Such reactions have been investigated experimentally as an alternativeway for the production of heavy and superheavy nuclei. The role of collisionorientation in the production cross sections of heavy nuclides is analyzedsystematically. Calculations show that the cross sections decrease drasticallywith increasing the charged numbers of heavy fragments. The transfer mechanismis favorable to synthesize heavy neutron-rich isotopes, such as nuclei aroundthe subclosure at N=162 from No Z=102 to Db Z=105.
