Abstract

The three components of the tensor analyzing power of the exclusive π^– meson photoproduction reaction on deuterons measured simultaneously in the photon energy ranges 300–900 MeV and 50–210 MeV are presented. 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.
