We have measured the absolute cross section {sigma}({theta}) and complete sets of spin observables {ital A}{sub 00{ital i}{ital j}} in {sup 3}He({ital p},{ital p}) elastic scattering at energies of 200 and 500 MeV. The observables depend on linear combinations of six complex scattering amplitudes for the {ital p}-{sup 3}He system and provide a severe test of current reaction models. The in-scattering plane observables ({ital A}{sub 00{ital m}{ital m}}, {ital A}{sub 00{ital l}{ital l}}, {ital A}{sub 00{ital l}{ital m}}, and {ital A}{sub 00{ital m}{ital l}}) are all in quantitative disagreement with fully microscopic nonrelativistic optical model calculations and nonrelativistic distorted wave Born approximation calculations.
