Incoherent pion photoproduction on the deuteron is studied for photon energies from threshold up to 1 GeV with special emphasis on polarization observables. The elementary γN→πN amplitude is taken from the MAID model. The influence of final state interactions on total and semi-exclusive cross sections d(γ,π)NN is investigated by including complete rescattering in the final NN- and πN-subsystems. For charged pion-production the influence of NN-rescattering is moderate whereas πN-rescattering is almost negligible. Much stronger influences of NN-rescattering are seen in neutral pion production, which is due to the elimination of a significant spurious coherent contribution in the impulse approximation. Sizeable effects are also found in some of the beam, target and beam-target asymmetries of the differential cross section.
