For use in applications such as pion photoproduction and inelastic exclusive pion scattering studies, a first-plus-second-order pion-nucleus optical potential is constructed by fitting the phenomenological p -dependent term to the m +--' C total and differential cross sections. It is demonstrated that such a potential is A universal (A is the atomic mass number) and well describes all available (total and elastic differential) pion scattering data for the He, Li, ' 0, Si, and Ca targets in a broad energy range 14( T (250 MeV.
