Abstract
Using a set of equations that couple the to the channel and satisfy two- and three-body unitarity, we have studied in detail the reaction , and and scattering. We find that the equations give a very good description of the differential cross sections and some of the polarization data for both and over the energy region MeV. We observe that for , higher partial waves () contribute significantly to both the differential cross section and analyzing power. Including the interaction and thus true absorption in elastic scattering, we find a cancellation between the pole and nonpole parts of the amplitude. A major part of the effect of true absorption is in , which contributes little to the absorption cross section. The sensitivity of the results to the state of the deuteron and the choice of the form factor is investigated. For scattering the agreement with the experimental phase shifts is better in the singlet than triplet channels. This is due to the absence of vector meson exchange in the calculation. The phase shift exhibits resonance behavior in the absence of a pole in the amplitude.
