Accurate Proton-Proton Differential Cross Sections Near 10 MeV

Abstract
In order to resolve inconsistencies in existing data, differential cross sections for the scattering of protons by protons have been measured at 9.690 and 9.918 MeV with accuracies near 0.4% relative and 0.6% absolute. Sources of error are given and the data are compared with previous experiments and theory.
