Résumé:Title screen
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 γ N → πN amplitude is taken from the MAID model. We investigate the influence of final state interactions on total and semi-exclusive cross sections d(γ,π )NN 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 are due to the elimination of a significant spurious coherent contribution in the impulse approximation. Sizable effects are also found in some of the beam, target, and beam-target asymmetries of the differential cross section.
