The optical model and deuteron stripping

A development is given which stresses the underlying similarity between the deuteron stripping theory on the one hand and direct interaction theory of inelastic nucleon scattering on the other. The assumption here is that both formulations are given in distorted Born approximation. Some implications for the form of the stripping theory, e.g., construction of the distorting potentials are discussed. The entire theory, as given, for the transition matrix element is first-order in the two-body scattering operators. Probable corrections to this description, such as those arising from multiple scattering, are discussed.
