The two approaches yield quite similar results for all of the observables with each projectile, including spin observables, suggesting the two models are physically equivalent. A new phenomenon in the analyzing power is confirmed in the results for 100 MeV scattering.9 pages, 4 figures, RevTeXNuclear Theorytext
