Absolute differential cross section measurements for proton-proton elastic scattering at 647 and 800 MeV

Abstract
Absolute differential cross sections for elastic proton-proton scattering have been measured in the center-of-mass angular interval from 20° to 90° at 647 and 800 MeV with overall uncertainties of ± (3-10)% and ± (3-5)%, respectively. The data at 800 MeV are the most accurate so far reported at that energy. Comparison is made to earlier measurements and contemporary phase-shift analyses.
