The (π-, π-n) and the (π+, π+p) reactions were studied on C, Fe, and Bi at 165 MeV by coincidence measurement o outgoing particles. The nucleon-knockout reaction is the dominant inelastic process at backward pion-scattering angles at this energy. The quasifree (π-, π-n) and (π+, π+p) cross sections were determined from the π-N an correlations. Their σqf-, π-n)/σqf+, π+p) ratio is consistent with unity for C and is larger than the N/Z ratio for the heavier nuclei.
