Mixed density expansion techniques previously used to study the spectroscopic content of the non-local knockout exchange amplitudes for nucleon-nucleus scattering in the plane wave approximation (PWA) are extended to the more realistic distorted wave approximation (DWA). This approach provides a clear basis for assessing specific spectroscopic consequences of the knock-out amplitudes and the means for developing suitable approximations to simplify the treatment of these amplitudes. Since the final reaction amplitudes are computed in momentum space, distortion effects are displayed in a form that allows for the most direct comparison between the strong nucleon-nucleus scattering reaction and the well understood electron-nucleus scattering reaction. As a specific application of the formalism, results are presented for polarization transfer observables for stretched excitations in light nuclei. Polarization transfer is a topic of current interest in nucleon-nucleus scattering. / Source: Dissertation Abstracts International, Volume: 55-03, Section: B, page: 0970. / Major Professor: Fred Petrovich. / Thesis (Ph.D.)--The Florida State University, 1993.
