The inclusive reactions /sup 12/C(..pi../sup + -/,..pi../sup + -/p) were studied at 245 MeV over a broad kinematic range by coincidence measurement of the outgoing particles. The ..pi../sup + -/-p angular correlations, proton energy spectra, and the ratio of positive- to negative-pion cross sections are all consistent with those expected from quasifree scattering. For positive pions, quasifree scattering accounts for (30 +- 3)% of the inclusive pion inelastic scattering to backward angles. The rest is attributed to the (..pi../sup +/,..pi../sup +/n) reaction and to multistep processes.
