Abstract

Since 1996 the GRAAL experiment is running at the ESRF, using a Linearly polarized photon beam produced by backscattering a laser beam on the electron beam in the storage ring. A liquid hydrogen target and a large acceptance detector are used. All sizeable photoproduction reactions are measured and analysed. We present the results of eta meson, one and two pions, and omega photoproduction, which are partly published or still preliminary. Predictions or fits of these data by theoretical models are given.
