    "abstract": "The photoproduction of a neutral pion on the deuteron is considered in the\nenergy region around the eta threshold, where a bump-like structure was\nobserved at very backward pion angles. Different dynamical aspects which may be\nresponsible for this phenomenon are analysed within a theoretical frame which\nincludes intermediate eta-NN configurations. The results show in particular,\nthat a three-body treatment of the eta-NN interaction is of special importance.",
