Two-nucleon scattering at intermediate energies of a few hundred MeV requires quite a few angular-momentum states in order to achieve convergence of e.g. scattering observables. This is even more true for the scattering of three or more nucleons from one another. An alternative approach to the conventional one, based on angular-momentum decomposition, is to work directly with momentum vectors, specifically with the magnitudes of momenta and the angles between them. We formulate and numerically illustrate [1] this alternative approach for the case of NN scattering using two realistic interaction models, the Argonne AV18 [2] and the Bonn-B [3) potentials. The momentum vectors enter directly into the scattering equation, and the total spin of the two nucleons is treated in a helicity representation with respect to the relative momenta q of the two nucleons. |
