CRITICAL COMPARISON OF EXPERIMENTAL-DATA AND THEORETICAL PREDICTIONS FOR N-D SCATTERING BELOW THE BREAKUP THRESHOLD

The theoretical approaches for studying N-d processes using realistic, semi-phenomenological NN potentials have matured considerably during the last few years. Accurate calculations of scattering observables ar e now feasible. Recently, high-quality measurements of N-d scattering at energies below the deuteron breakup threshold became available. The refore, a detailed comparison between theory and experimental data can now be performed. In this paper the various sets of experimental data for the N-d differential cross section, and the vector and tensor ana lyzing powers are examined in a critical way in the incident nucleon e nergy range from 1 to 3 MeV. In order to identify possible inadequacie s of the interaction models adopted, phase-shift analyses were perform ed and compared to the theoretical parameters.
