Recent developments in few-nucleon systems Original Research Article

N − d elastic scattering is studied at different energies using one of the modern NN interactions, the Argonne v18 which explicitly includes the magnetic moment interaction between two nucleons. This interaction, which has been often neglected in the description of the few-nucleon continuum, produces sizable modifications in some elastic observables. Its effects, as well as those produced by the Coulomb potential, are analyzed as a function of energy. The magnetic moment interaction produces appreciable effects in p − d scattering at low energies but they are very small above 10 MeV. Above 65 MeV Coulomb effects can be observed only in specific observables as for example T21.
