Total and differential cross-sections are presented. The eta mesons are detected in two decay modes, in eta -> 2gamma and in eta -> 3pi0 -> 6gamma. The cross-sections vary slowly as functions of energy and eta production angle suggesting that only few resonances make significant contributions to the cross-section. For photon energies above 1.5GeV, the differential cross-sections show a strong forward peak due to meson exchanges in the t channel. A comparison of the eta-photoproduction cross-sections with SAID and MAID as well as with a partial-wave analysis performed on our data in combination with other data sets shows good agreement. The Bonn-Gatchina partial-wave analysis suggests that the largest contribution to eta photoproduction for energies below 3GeV proceeds via three resonances, the well-known N(1535)S11, via N(1720)P13, and a suggested N(2070)D15.en620539Photoproduction of eta-mesons off protonsjournal article
