| Popis: | Photoproduction of pi0-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 S11(1535) for pi0-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 D33 wave with a relatively small admixture of positive parity resonances. Comparison with recent experimental results for the photon beam asymmetry is carried out. Comment: 14 pages, 11 figures |
