TENSOR POLARIZATION OF A TARGET IN THE GAMMA-D-]D-PI-0 PROCESS

Manifestations of dibaryon resonances with Jp = 2+, 3- in the angular and energy dependences of the gamma-d-->d-pi-degrees reaction asymmetries which are due to the tensor polarization of a target (initial photons are nonpolarized), are studied. The spin structure of the resonance amplitudes includes the photons with minimal multipolarity and pi-degrees-mesons with minimal orbital momenta. The impulse approximation amplitude for the gamma-d-->d-pi-degrees process is parametrized in terms of the deuteron form factors and isovector amplitudes of the gamma-N-->N-pi process. Dependence of the amplitude on polarization vectors of photon and deuterons is found. A scale of effects of dibaryon resonances in all the independent asymmetries due to the tensor polarization, is revealed at E-gamma < 0.8 GeV.
