Differential cross sections and polarised photon beam asymmetries for eta, pi(0) and pi(1) photoproduction on the proton, produced by the GRAAL Collaboration, are presented. The results cover wide angular and enegy ranges of 40-170degrees and 550-1496 MeV (707-1496 MeV for eta) respectively, and exhibit an unprecedented level of accuracy. The results are compared with predictions of several models.

Abstract
Differential cross sections and polarised photon beam asymmetries for eta, pi(0) and pi(1) photoproduction on the proton, produced by the GRAAL Collaboration, are presented. The results cover wide angular and enegy ranges of 40-170degrees and 550-1496 MeV (707-1496 MeV for eta) respectively, and exhibit an unprecedented level of accuracy. The results are compared with predictions of several models.
