Turinge, V. Vegna (2010) Abstract The γp → η‧p reaction was studied near the threshold, in the 1.44 GeV> Eγ < 1.55GeV energy range with the tagged photons of the former GRAAL experiment. The two neutral decays γγ(Γi/Γ = 2.10 ± 0.12%) and π0π0η(Γi/Γ = 20.7 ± 1.2%) were analized and preliminary results of the beam asymmetry were extracted together with the invariant masses.
