Abstract

The effect of binding and multiple-scattering corrections to the impulse approximation, as well as of corrections due to the presence of off-the-energy- shell matrix elements is discussed for the case of scattering from a deuteron or other two-particle system. Those binding and multiplescattering corrections that have the form of double scattering are evaluated expllcitly for the case of quasi- elastic p-d scattering at 145 Mev, and their inclusion is found to give agreement with the experimental results on the cross section and polarization despite the fact that estimates of the triple-scattering corrections show they are of magnitude comparable to the effects that are included. The double-scattering corrections to the cross section, polarization, and R and A parameters for quasi- elastic n-d scattering at the same energy are also given. The off-theenergy- shell corrections are evaluated numerically, and are found to be too small to be observed because of experimental errors and uncertainty in the calculation of the multiple-scattering corrections.
