Transfer of nucleons between heavy nuclei at large distances

Dynamical and structural aspects of transfer reactions between heavy nuclei are discussed. At the internuclear distances for which the dissipation is still small, cold multinucleon transfer offers the possibility to study the coupling of structural and dynamical aspects of the nuclear two-center system. The experimental results of neutron and proton transfer are inspected for a variety of systems. Examples for the enhancement of two-nucleon transfer due to the pairing interaction are shown and connections to the nuclear Josephson-effect are discussed
