Abstract
An energy-dependent amplitude analysis of elastic-scattering data in the pion energy range from 486 to 870 MeV was carried out. Using a careful treatment of Coulomb effects to describe the Coulomb nuclear interference together with the constraints from the forward amplitude by dispersion relations allows a stringent consistency check of the data. In general a satisfactory description of the data was achieved, but recent elastic-scattering data need considerable normalization factors to fit into the framework. The still not measured data as well as the data at 870 MeV are predicted. Phase shifts are calculated by partial wave projection of the amplitudes. The partial waves are summed up to obtain the total, total-elastic and total-inelastic cross sections.
