Photoproduction of \ensuremathπ0\ensuremathη on protons in the energy range from threshold to 1.4 GeV is discussed. The data for representative angular distributions recently obtained at MAMI C are analyzed using an isobar model. The isobars considered are \ensuremathΔ(1232) and S11(1535) for \ensuremathπ0p and \ensuremathηp states, respectively. In accordance with the results of earlier works, the main features of the reaction are explained through the dominance of the D33 wave with a relatively small admixture of positive parity resonances. Comparison with recent experimental results for the photon beam asymmetry is carried out.
