Photoproduction of {pi}{sup 0{eta}} 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 {Delta}(1232) and S{sub 11}(1535) for {pi}{sup 0}p and {eta}p states, respectively. In accordance with the results of earlier works, the main features of the reaction are explained through the dominance of the D{sub 33} wave with a relatively small admixture of positive parity resonances. Comparison with recent experimental results for the photon beam asymmetry is carried out.
