We measured the polarization of the recoil proton in the reaction ..gamma..p..-->..p..pi../sup 0/ with a beam of linearly polarized photons obtained with the aid of coherent bremsstrahlung from a diamond crystal in the Khar'kov linear electron accelerator. The experimental values of the cross-section asymmetry epsilon, of the asymmetry T/sub y/ on a polarized target, and the recoil-proton polarization components P/sub y/ and P/sub x/'z' are obtained at a photon energy 500 MeV and at c.m.s. pion-emission angles 105, 120, and 140/sup 0/ and are compared with the predictions of various multipole analyses.
