N-d elastic scattering at low-energies with local and non-local realistic nuclear interactions

The application of the hyperspherical harmonic approach to the case of the N −d scattering problem is described. The nuclear Hamiltonian includes local and non-local two- and three-nucleon interactions. Also, Coulomb repulsion is included in the p − d case. Accurate calculation for p − d and n − d cross section and polarization observables at two center-of-mass energies are performed and the theoretical results are compared with the available experimental data. A satisfactory agreement between theory and experiment is found, except for the vector polarization observables. A quantitative estimate of the agreement or disagreement between theory and experiment is obtained performing a chi^2 analysis
