Popis: A semiclassical model applied to backward inelastic pion-nucleus scattering reproduces the general features of the (..pi..,..pi..') data and suggests a way of extracting the fractions involving pion multiple scattering, nucleon final state interactions, and unperturbed quasifree scattering. In order to fit the knockout (..pi../sup +/,..pi../sup +/p) coincidence data, the free NN cross sections must be reduced by a factor which rapidly increases with A, implying a long mean free path for the outgoing nucleon in heavy nuclei.
