Abstract

The GRAAL tagged and polarized gamma beam has been operating with a maximum energy of 1100 MeV. For the first time asymmetry results in eta photoproduction were obtained and will be shown. Interesting results have also been obtained for pi(0) and pi(+) photo-production, that largely confirm the already existing ones, but also extend in not yet explored angular and energetic regions, especially for backward scattering and energies greater than 900 MeV.
