N2 - The paper presents new results for the T20 analyzing power tensor component of the γd→pnπ0 reaction in the photon energy range of 300 MeV < Eγ < 500 MeV. The experimental statistics accumulated in 2013 at the VEPP-3 accelerator-storage complex using an internal tensor-polarized gaseous deuterium target has been used. The reaction events are identified by the coincidence registration of the proton and two gamma quanta from the neutral pion decay. To determine the T20 component, the asymmetry of the yields with respect to the change in the sign of the tensor polarization of the deuterium target is measured. Experimental results are compared with the theoretical calculations for the MAID 2007 model of the amplitude used as the elementary pion-nucleon photoproduction amplitude and contributions of pion-nucleon and nucleon-nucleon rescattering are taken into account.
