The nonrelativistic multiple scattering formalism of Watson and Kerman, McManus, and Thaler is applied to the deuteron-nucleus elastic scattering system. An optical potential is constructed to second order in the nucleon-nucleon effective interaction t matrix and is organized in such a way that the usual Watanabe folding potential appears as the leading term. The Watanabe folding potential is constructed by integrating nucleon-nucleus optical potentials evaluated at half the deuteron incident kinetic energy over the deuteron s-state wave function. Corrections to the folding potential are identified which arise from deuteron-nucleon double scattering effects, the deuteron d state, virtual deuteron breakup, additional nuclear medium effects, additional target nucleon correlation effects, and relativistic processes. Many of these corrections do not appear in folding model approaches based on effective, rather than microscopic, deuteron-nucleus Hamiltonians. These additional multiple scattering corrections are second order in the nucleon-nucleon t matrix as is the case for the virtual deuteron breakup process which is often included in numerical calculations. Estimates of several of these additional multiple scattering corrections are provided for 700 MeV deuteron-nucleus elastic scattering. Most are found to be quite small. However, the additional effects of the nuclear medium beyond that already included in the input nucleon-nucleus optical potentials are significant and are comparable in magnitude to the effects of virtual deuteron breakup. It is intended that this multiple scattering approach be applied to deuteron-nucleus elastic scattering at energies of several hundred MeV.
