Abstract

Three components of the tensor analyzing power of the exclusive π meson photoproduction on a deuteron, γd→ppπ, are measured simultaneously for the photon energy range (300–900) MeV, detecting a pair of protons in the energy range (50–200) MeV. The experiment made use of an internal tensor-polarized deuterium gas target of the VEPP-3 electron storage ring and the two-proton coincidence recording method. The results obtained are compared with theoretical predictions within the framework of the diagrammatic approach.
