Abstract: Preliminary results on the beam asymmetry Σ for η and π0 photoproduction on the proton and the neutron in the deuteron in a quasi free kinematics regime have been obtained. Very preliminary results will be presented on the status of art of the GRAAL search for the two members of the exotic penta-quarks anti-decuplet, the P11 and the Θ+.
