Description
An energy-dependent phase shift analysis of π±-4He elastic scattering data up to an energy Tπ=260 MeV was carried out. Using a careful treatment of Coulomb effects to describe the Coulomb nuclear interference we reexamined the constraints to the π-4He forward scattering amplitude f0 by dispersion relations. This allows a stringent consistency check of the data. A satisfactory description of the data could only be achieved assuming large error bars of the total cross section measurements and allowing normalization factors for the differential cross section data
