The quasi-free break-up of deuteron was used to study the neutron-induced 6Li + n reaction via the 2H(6Li, α3H)p. The aim of the experiment was to check whether the deuteron can be considered as a source of virtual neutrons. This was done by studying the excitation function of the 6Li(n, α)3H two-body reaction at low energy where the resonance corresponding to the excited level at 7.454MeV of 7Li is present. Two experimental runs were performed at the Laboratori Nazionali del Sud (LNS) in Catania, Italy. In both experiments, the energy and the position of the outgoing a and 3H particles were measured and the kinematics were reconstructed assuming a proton as the third particle. The quasi-free events were selected in order to reconstruct the 6Li(n, α)3H cross section in the center-of-mass energy by using the plane wave impulse approximation approach. The obtained cross section is in very good agreement with the directly measured one.
