Calculations of elastic n-d scattering for the Reid potential

A peturbation scheme is used to study neutron-deuteron elastic scattering with the Faddeev equations in momentum space. The pure s-wave parts of the two-nucleon T-matrix are treated in an exact way, while the higher partial-wave components are retained in first order. This is done for the full Reid soft-core potential. The lab energies considered in this study are between 5 and 50 MeV. It is found that the perturbation method can give insight in the sensitivity to details of the potential, and at higher energies can give quantitatively reliable results, for most of the observables.
