We report the measurement of differential cross sections for ω and η  photoproduction from protons at backward angles (−1.0 < cosX C.M < −0.8) using linearly polarized photons at Eγ = 1.5–3.0 GeV. The differential cross sections for ω mesons are larger than the predicted u-channel contribution based on amplitude analysis in the energy range 2.0 ≤ …
