M1040 1 37 COMMENT In the present study the experimental statistics M1040 1 38 for the reaction d(g,PI0pn) accumulated at VEPP-3 M1040 1 39 in 2013 was used. Unlike the previous measurements, M1040 1 40 the main goal of the last experiment was to study M1040 1 41 the coherent PI0 photoproduction on a M1040 1 42 tenzor-polarized deuterium target using an M1040 1 43 unpolarized photon beam. In contrast to the M1040 1 44 experiment of 2003, in which only two final nucleons M1040 1 45 were detected, in the present case the proton and two M1040 1 46 g-quanta from the PI0 decay were detected in M1040 1 47 coincidence.
