Abstract

The spin rotation parameter R in elastic proton-proton scattering has been determined at incident momenta 6 and 16 GeV/c in the interval from t = −0.18 (GeV/c)2 to −0.54 (GeV/c)2. Rpp at 16 GeV/c is close to the val obtained for R in πp elastic scattering at the same incident momentum. Equality of Rpp(s, t) and Rπp(s, t) is expected if Pomeron exchange dominates and if factorization holds. The t-dependence of R at 16 GeV/c is consistent with weak helicity flip.
