Abstract

The Sternheim-Silbar linear transport model for calculating the effect of final-state charge exchange of the struck nucleon in (π,πN) reactions has been reexamined. It is demonstrated that for C12, the effect ranges from only 10% at low pion energies to 4% at the (3,3) resonance and plays a minor role in determining the magnitude of the inclusive cross sections. A semiclassical linear transport model is used to calculate the ππ+ ratio for a clean, one-step nucleon knockout. Unlike the Sternheim-Silbar calculation these results are in very good agreement with intranuclear cascade model predictions.

NUCLEAR REACTIONS σ(π,πN) ratios, (3,3) resonance, final state interaction, nucleon removal, one-step quasi-free and intranuclear cascade calculations.
