✦ Synopsis

This paper presents the results of experimental investigations of (p, pn), (p, pα) and (p, p 6 He) reactions with relativistic 6 He and 8 He beams impinging on a hydrogen target. Information on the structure of extremely neutron-rich nuclei was obtained by using the unique characteristic of quasi-free scattering processes and inverse kinematics. For the first time, momentum distributions of complex clusters inside 6 He and 8 He were measured. Spectroscopic factors for valence neutrons, αand 6 He clusters were deduced from the experimental data. They demonstrate that the filling of the * Corresponding author.
