We present recent Graal results on beam-polarization asymmetries in the photoproduction of η meson on protons and neutrons in Hydrogen and Deuterium for the incoming photon energy range from threshold to 1.5 GeV. Data have been obtained using the tagged and linearly polarized photon beam and the large solid angle apparata of the Graal facility, located at the ESRF in Grenoble (France). The comparisons between the free and bound (in the deuteron)

Abstract

We present recent Graal results on beam-polarization asymmetries in the photoproduction of η meson on protons and neutrons in Hydrogen and Deuterium for the incoming photon energy range from threshold to 1.5 GeV. Data have been obtained using the tagged and linearly polarized photon beam and the large solid angle apparata of the Graal facility, located at the ESRF in Grenoble (France). The comparisons between the free and bound (in the deuteron)
