Investigation of the 6He structure in quasi free scattering reactions
Momentum correlations inherent to the 6He constituents in the ground state of this nucleus were studied in the quasi-free scattering (QFS) reaction 4He(6He, 2α)2n at 6He beam energy of 25 MeV/nucleon. A detailed study of nucleus structure was performed for the first time in QFS reactions with an unbound spectator. The Plane Wave Impulse Approximation was used in analyzing the experimental data. It was shown that the experimental data are described by model calculations in which the two neutron final state interaction is taken into account. t + t and t + d + n configurations were also studied in the 4He(6He, tα)t and 4He(6He, tα)dn QFS reactions.
