Abstract
The analyzing power A(N) Of proton-proton elastic scattering in the Co ulomb-nuclear interference region has been measured using the 200-GeV/ c Fermilab polarized proton beam. A theoretically predicted interferen ce between the hadronic non-spin-flip amplitude and the electromagneti c spin-flip amplitude is shown for the first time to be present at hig h energies in the region of 1.5 X 10(-3) to 5.0 X 10(-2) (GeV/c)2 four -momentum transfer squared, and our results are analyzed in connection with theoretical calculations. In addition, the role of possible cont ributions of the hadronic spin-flip amplitude is discussed.
