The inclusive reactions C12(,p) were studied at 245 MeV over a broad kinematic range by coincidence measurement of the outgoing particles. The -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 (+,+n) reaction and to multistep processes.
