Preliminary results are reported of the measurement of proton polarization in the reaction y+p—»7r°+ρ on a linearly polarized beam of photons with a polarization vector inclined 45° (135°) to the reaction plane. The longitudinal component of the polarization vector (Pz) is obtained. The experimental results are compared with the Schwela dispersion analysis and with the Walker phenomenological analysis.
