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 thres hold. The method consists in an expansion of the wave function in term s of the pair correlated hyperspherical harmonic basis. The reactance matrix of the system is found by means of the Kohn variational princip le. As a difference with the Faddeev technique, the inclusion of the C oulomb interaction does not give any additional difficulty. The accura cy of the method allows for a detailed comparison with experimental re sults and for the evaluation of Coulomb effects.
