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.

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.
