Abstract.
The paper presents results of a double polarization experiment to extract an asymmetry of the \(\pi^{-}\)-meson photoproduction on a tensor-polarized deuteron by a linearly polarized photon. The energy of photons lies in the range (300-700) MeV. The measurements were performed on the internal tensor-polarized deuterium target in the VEPP-3 electron-positron storage ring for the electron beam energy equal to 2 GeV. In the experiment, two protons and a scattered electron were detected in coincidence. The results of the measurement are compared with theoretical predictions made in the framework of impulse approximation, taking into account the \(\pi N\) and NN-rescattering in the final state.
