Sažetak
The GRAAL experimental set-up consists of a polarized and tagged photon beam that covers an energy range from a minimum of 600 MeV up to a maximum of 1500 MeV, of a liquid Hydrogen or Deuterium target and of the 4 pi Lagrange detector optimized for photon detection It allows the study of pseudo-scalar and vector meson photoproduction on the nucleon in the energy range corresponding to the second and the third resonance regions In the following, the Sigma beam asymmetries in eta and pi(0) photoproduction on quasi-free nucleon are shown. Also single and double polarization observables in K(+)Lambda photoproduction on free proton are shown, they are important to confirm the role of new or poorly known resonances in the 1900 MeV mass region
