CROSS-SECTION, POLARIZATION OBSERVABLES, AND PHASE-SHIFT PARAMETERS IN P-D AND N-D ELASTIC-SCATTERING

Differential cross section, polarization observables, and phase-shift and mixing parameters up to L = 4 and J less than or equal to 11/2 are calculated for p-d and n-d elastic scattering below the breakup threshold. The method consists in an expansion of the wave function in terms of the pair correlated hyperspherical harmonic basis. The reactance matrix of the system is found by means of the Kohn variational principle. As a difference with the Faddeev technique, the inclusion of the Coulomb interaction does not give any additional difficulty. The accuracy of the method allows for a detailed comparison with experimental results and for the evaluation of Coulomb effects.
