A2 Collaboration at MAMI.
High statistics angular distributions and total cross sections for
the photoproduction of $\pi^0$ mesons off the deuteron with
coincident detection of recoil nucleons have been measured for the
first time. The experiment was performed at the tagged photon beam
of the Mainz Microtron (MAMI) for photon energies between 0.45 and
1.4 GeV, using an almost 4$\pi$ electromagnetic calorimeter composed
of the Crystal Ball and TAPS detectors. A complete kinematic
reconstruction of the final state removed the effects of Fermi
motion. Significant effects from final-state interactions (FSI)
were observed for participant protons in comparison to free proton
targets (between 30% and almost 40%). The data in coincidence with
recoil neutrons were corrected for such effects under the assumption
that they are identical for participant protons and neutrons.
The total overall systematic uncertainty was estimated at 7%.
