The elementary $\\gamma N\\to\\pi N$ amplitude is taken from the MAID model. The influence of final state interactions on total and semi-exclusive cross sections $\\vec d(\\vec\\gamma,\\pi)NN$ is investigated by including complete rescattering in the final $NN$- and $\\pi N$-subsystems. For charged pion-production the influence of $NN$-rescattering is moderate whereas $\\pi N$-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.", "revisions": [ { "version": "v1", "updated": "2005-06-06T12:36:14.000Z" } ], "analyses": { "subjects": [ "13.60.Le", "25.20.Lj", "21.45.+v", "24.70.+s" ], "keywords": [ "incoherent pion photoproduction", "final state rescattering", "polarization observables", "differential cross section", "significant spurious coherent contribution" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
