Abstract

Integral cross sections for the elastic scattering of π⁺ by protons into angles greater than 20° or 30° (lab) have been measured by the beam-attenuation technique over the energy range of 45-126MeV. The measurements are aimed at providing independent checks on the absolute normalization of differential cross sections, where discrepancies exist between different data sets. Comparisons with predictions made with existing phase shifts show very good agreement with the dispersion-relation constrained phase shifts of the Karlsruhe group.
