The quasi-free break-up of deuteron was used to study the neutron-induced Li-6 + n reaction via the H-2(6Li, alpha H-3)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 Li-6(n, alpha)H-3 two-body reaction at low energy where the resonance corresponding to the excited level at 7.454MeV of Li-7 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 alpha and H-3 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 Li-6(n, alpha)H-3 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.

Abstract
The quasi-free break-up of deuteron was used to study the neutron-induced Li-6 + n reaction via the H-2(6Li, alpha H-3)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 Li-6(n, alpha)H-3 two-body reaction at low energy where the resonance corresponding to the excited level at 7.454MeV of Li-7 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 alpha and H-3 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 Li-6(n, alpha)H-3 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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
