Abstract
The influence of final-state NN and $\pi N$ rescattering in incoherent pion photoproduction on the deuteron has been investigated. For the elementary photoproduction operator an effective Lagrangian model is used which describes well the elementary reaction. The interactions in the final two-body subsystems are taken in separable form. While NN rescattering shows quite a significant effect, particularly strong for neutral pion production, $\pi N$ rescattering is almost negligible. Inclusion of such effects leads to an improved and quite satisfactory agreement with experiment.
