Results are presented of the measurement of the energy dependence of the proton polarization in the reactions (γ,ρπ0) and (γ,ρπ~) on l2C. The measurements were made by registering the pions and protons in coincidence. No strong influence of the interaction in the final state on the proton polarization was observed. The proton polarization in the reaction (γ, ρπ ) agrees with the predictions of Walker's analysis, and no reversal of its sign in the region of the second (π Ν) resonance was observed.
