PHENOMENOLOGICAL NONLOCAL NUCLEON-NUCLEON INTERACTIONS AND THE NEUTRON-DEUTERON ELASTIC-SCATTERING

Phenomenological ''inside non-local, outside Yukawa-tail'' N-N interac tions, which fit the N-N data and produce the correct triton binding e nergy, are tested for elastic n-d scattering observables in the energy range of E-n = 3.01-22.7MeV. The sensitivity of the different measura ble quantities to the type and to the different components of the N-N interaction is investigated. Some of the possible modifications of the triplet P-wave interactions necessary to reproduce the neutron vector analyzing power are found. The new INOY S-1(0) and S-3(1)-D-3(1) inte ractions together with appropriate parametrizations of the higher part ial waves seem to reproduce the experimental data better than the corr esponding components of the Argonne upsilon(18) potential.
