Abstract
We report here a measurement of the analyzing power Ay in 185 MeV elastic proton-proton (pp) scattering at forward angles (2.5°–10.5° in the laboratory). In this angular range the Coulomb and nuclear amplitudes are of similar magnitude and measurements of polarization observables allow separation of the real and imaginary components of the nuclear amplitudes by their interference with the known Coulomb amplitude.[1] Precise measurements at such small angles can be difficult due to the presence of beam halo or scattering from target materials other than hydrogen. In the present experiment we have used both a windowless gas jet target and coincident detection of the low energy proton at large angles to eliminate these backgrounds.
