Measurement and semi-phenomenological analysis of the 2H(α, pα)n reaction at 18 MeV

Abstract

Kinematically complete measurements of the 2(α, pα)n reaction at 18 MeV lab energy have been performed at various pairs of angles θ p and θ α. The p-α quasi-free scattering peak cross sections show an angular dependence similar to that predicted in the plane wave impulse approximation. From the analysis in a modified impulse approximation, it is found that two correction terms reflecting the effects of the three-nucleon transfer reaction and 6Li resonances are necessary to reproduce the data, as was the case for the 15 MeV 2H(α, pα)n reaction.
