摘要：

The experimental status of baryon resonances is reviewed. Different reaction channels and the extraction of baryon resonance parameters are discussed. For single pion photoproduction the contribution of different observables are shown pointing out the importance of polarization observables. The η-cusp is described as an example of a threshold effect. Experimental techniques in connection with a tagged photon beam are surveyed. As examples new experiments at the stretcher accelerator ELSA in Bonn are briefly discussed. © 1990.
