Photoproduction of ω mesons from Be, C, Al, Cu, and Pb has been studied at a mean energy of 6.8 GeV. The t distributions show a forward peak characteristic of a coherent diffraction mechanism, but also a considerable cross section at large t characteristic of an incoherent production mechanism. The ratio of cross sections for coherently photoproduced ρ⁰ mesons to ω mesons is 11.8 ±{} 1.3 compared with the simple SU(3) prediction of 9.
