摘要：

Using the framework of the coupled reaction channels (CRC) the elastic scattering and the elastic transfer in the system He-6 + He-4 measured at E = 151 MeV have been analysed. It is shown that the structure observed in the backward range of the angular distributions is influenced by the interference of the elastic 2n-transfer with a two-step process passing through the 2(+) excitation in He-6. The two-neutron transfer mechanism is studied in the microscopic approach and it is found that for the ground-state transition the one step dominates by a factor 10 over the two-step mechanism at this energy.
