Experiments with electromagnetic probes are promising to search for new baryon states and to determine the properties of baryon resonances. The Crystal Barrel experiment at ELSA is very well suited to investigate final states with neutral mesons decaying into photons. Interesting results on baryon resonances have been obtained. In particular a new D 15 (2070) decaying into pη was recently observed. In multi-meson final states such as pπ 0 π 0 and pπ 0 η baryon cascades occur. Baryon resonances
