The application of the hyperspherical harmonic approach to the case of the N-d scattering problem below deuteron breakup threshold is described. The nuclear Hamiltonian includes two-and three-nucleon interactions, in particular the Argonne upsilon(18), the N3LO-Idaho, and the V(low-k) two-nucleon, and the Urbana IX and N2LO three-nucleon interactions. Some of these models are local, whereas some are nonlocal. Also electromagnetic effects are included. Accurate calculations for many scattering observables at various center-of-mass energies are performed and the results are compared with the available experimental data. Furthermore, a chi(2) analysis of some of the Hamiltonian models has been performed to compare their capability to describe the scattering process.

Abstract
The application of the hyperspherical harmonic approach to the case of the N-d scattering problem below deuteron breakup threshold is described. The nuclear Hamiltonian includes two-and three-nucleon interactions, in particular the Argonne upsilon(18), the N3LO-Idaho, and the V(low-k) two-nucleon, and the Urbana IX and N2LO three-nucleon interactions. Some of these models are local, whereas some are nonlocal. Also electromagnetic effects are included. Accurate calculations for many scattering observables at various center-of-mass energies are performed and the results are compared with the available experimental data. Furthermore, a chi(2) analysis of some of the Hamiltonian models has been performed to compare their capability to describe the scattering process.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
