An experiment to measure component T 20 of the tensor analyzing power for the coherent photo-production of neutral pions on polarized deuterons is described. The measurements cover the photon energies in the ranges E γ = 200-500 MeV and E γ = 300-600 MeV, and the emission angles of neutral pions in the ranges = θc.m. π0 = 100°-140° and = θc.m. π0= 60°-65°, respectively. The experiment uses a hyperfine internal gas polarized target. Detectors of neutral pions and deuterons register these particles in coincidence. The target's degree of polarization and luminosity is measured by detecting elastic electron-deuteron scattering at low momentum transfer. A selection of the preliminary results is presented.
