POLARIZATION EFFECTS IN THE 3He(d,p)4He FUSION REACTION

We calculate the cross section of the reaction 3He(d,p)4He at very low energies using the three-body Faddeev formalism in which the target nucleus 3He is considered as a cluster with spin 1/2 and the projectile deuteron as a proton and a neutron. For the n-p interaction we adopted the AV14 potential while for the p-3He and n-3He channel we constructed effective potentials based on the well known Resonating Group Method (RGM). Since the n-3He and p-3He effective potentials are essentially different, the three-body system is treated as a three-channel problem. A resonance state is found using the 1S0 and 3S1-3D1 input states for the n-p and the 1S0 and 3S1 input states for both nucleon-cluster interactions. Coulomb effects were taken into account for the initial and the final states only. The polarization effects on the total cross section around the resonance region are discussed.
