Abstract

At the GRAAL facility, a polarised and tagged gamma ray beam is produced in the energy range from 500 MeV up to 1500 MeV. Results of beam polarisation asymmetries and cross sections for the photoproduction of eta and pi(0) on the proton are presented. These very precise measurements cover the angular range 30 degrees-150 degrees, providing stringent constraints to theoretical models.
