Abstract :
Differential cross sections for the elastic scattering of 6He exotic nuclei from a gaseous helium target has been measured in a wide angular range in the CM system at a 6He beam energy of 151 MeV. The large cross-sections obtained at backward angles are discussed in terms of a two-neutron exchange process. The results of DWBA calculations show that this effect can account for the cross sections obtained between 120° and 160° assuming the spectroscopic factor to be about 1 for the di-neutron cluster as was predicted by theory for 6He.
