Coherent photoproduction of vector mesons ρ0, ω, φ, and ρ′ on deuterium was studied using the SLAC 82-in. bubble chamber exposed to linearly polarized photons at 5.5 GeV. The reaction channel γd→π+π−d was studied in detail. Nine independent density-matrix parameters have been determined from the ρ0 decay distribution. ρ production in this channel was found to proceed almost completely through natural-parity exchange for |t|≤0.25 GeV2 and conserve s-channel c.m. helicity for |t|≤0.15 GeV2. A measurement of differential cross section for this channel has been made.
