Coherent pion photoproduction, d({gamma},{pi}{sup 0})d, is calculated in a coupled channels approach in momentum space using an elementary production operator that includes Born terms, vector meson exchange, and M1/E2 {Delta}-resonance excitation. The final state interaction is treated in the Kerman-McManus-Thaler multiple scattering approach that describes {pi}d elastic scattering well. Differential cross sections are found to agree well with existing ({gamma},{pi}{sup 0}) data. The polarization observables {Sigma},iT{sub 11} and the tensor analyzing powers are predicted for forthcoming experiments. A number of transparent relationships between polarization observables and the elementary production operator is derived. Finally, calculations are performed for coherent {eta} photoproduction, d({gamma},{eta})d, in the threshold region which agree well with a very recent Mainz experiment. {copyright} {ital 1997} {ital The American Physical Society}
