Abstract
Spectra of coincident charged particles from the reactions induced by a 18 MeV 6He beam incident on the 6Li and 7Li targets were measured. A strong contribution to the 6He-d spectrum may be interpreted as the 6He quasi-free scattering off the deuteron in the 6Li nucleus. This would then be the first observation of the quasi-free scattering of fragile radioactive nuclei on clusters in target nuclei.
