Study of heavy di-nuclear systems

Abstract : We investigated di-nuclear system formation with successive nucleon transfer at beam energies at and below the barrier in the superheavy systems 64 28Ni +207 82Pb (Zproj.+ Ztarget = 110) and 238 92U +238 92U (Zproj.+ Ztarget = 184). In both collision systems we observed a massive transfer of nucleons correlated with the dissipation of the entire kinetic energy. The results are in accordance with the two-center shell model which assumes the formation of a di-nuclear system as first step to fusion. The experiments have been performed at the velocity filter SHIP (GSI) and at the VAMOS spectrometer (GANIL).
