Abstract
Incoherent eta-photoproduction on the deuteron is studied for photon e nergies from threshold up to 720 MeV. The elementary gamma N --> eta N amplitude is constructed in the frame of a conventional isobar model. Effects of final state interaction are investigated and their role in the cross section as well as in polarization observables is found to be important. Inclusion of such effects leads to a satisfactory agreem ent with experimental data in the near threshold region. In addition, recent experimental results on the coherent reaction d(gamma, eta)d ar e discussed.
