| Zusammenfassung: | The possibilities of a model-independent partial wave analysis for pion, eta
or kaon photoproduction are discussed in the context of complete experiments.
It is shown that the helicity amplitudes obtained from at least 8 polarization
observables including beam, target and recoil polarization can not be used to
analyze nucleon resonances. However, a truncated partial wave analysis, which
requires only 5 observables will be possible with minimal model assumptions. |
