Magnetic moments of excited baryons

The explanation of the nucleon’s resonance spectrum is a long standing challenge. Magnetic moments of resonances are a valuable testing ground for baryon structure calculations. We have shown in a former experiment that the extraction of the Δ⁺(1232) magnetic dipole moment is feasible via the measurement and analysis of the reaction γp→π⁰γ^′p, in which the photon γ^′ carries the desired information. Such an experiment has been repeated with high precision using the Crystal Ball and TAPS detectors at the MAMI accelerator facility. Preliminary results will be presented. Furthermore, the perspectives for accessing the magnetic moment of the S₁₁(1535) resonance in radiative η photoproduction γp→ηγ^′p will be discussed.
