Coherent photoproduction of eta -mesons from the deuteron has been measured from threshold up to E/sub gamma / approximately=750 MeV using the photon spectrometer TAPS at the tagged photon facility at the Mainz microtron MAMI. For the first time, differential coherent cross-sections have been deduced from the coincident detection of the eta -meson and the recoil deuteron. A missing-energy analysis was used for the suppression of background events so that a very clean identification of coherent eta -photoproduction was achieved. The resulting cross-sections agree with previous experimental results except for angles around 90 degrees in the gamma d c.m. system where they are smaller. They are compared to various model calculations.
