Meson photoproduction at GRAAL: preliminary results

Abstract : A polarised and tagged $\vec \gamma $ ray beam is produced at GRAAL with energies ranging from 500 MeV up to 1500 MeV. Results of beam polarisation asymmetries and cross sections for the photoproduction of pseudoscalar mesons on the proton are presented. These very precise measurements cover the angular range 30°–150°, providing stringent constraints to theoretical models.
