Abstract：
The Isobar model of G.E.Brown et al. for π-nucleus scattering is extended to describe the (π, N) reactions at intermediate energies. The many-body effects are treated by using a phenomenological approximation. The influences of some factors upon the differential reaction cross sections are investigated. These include nonstatic correction, nucleon correlation wavefunction and distorted effect of the outgoing nucleon. The angular distributions of ³He(π ^－,n) ²H reaction at 100—300MeV are calculated. The theoretical calculations are essentially consistent with experiments.
