Abstract [en]

Angular distributions for In and 2n transfer are reported for the He-6 + Cu-65 system at E-lab = 22.6 MeV. For the first time, triple coincidences between a particles, neutrons, and characteristic gamma rays from the targetlike residues were used to separate the contributions arising from In and 2n transfer. The differential cross sections for these channels, elastic scattering, and fusion were analyzed using a coupled reaction channels approach. The large measured ratio of the 2n-to-1n cross section and the strong influence of 2n transfer on other channels indicate that the dineutron configuration of He-6 plays a dominant role in the reaction mechanism.
