Abstract

Recent experimental results for the in-medium properties of nucleon resonances are discussed. The experiments were done with the TAPS detector at the tagged photon beam of the MAMI accelerator in Mainz. Measured was the photoproduction of mesons (final states π 0 X, η X, 2π 0 X and π 0 π± X) from the nuclei 12C, 40Ca, 93Nb and 208Pb up to the second resonance region. The results were analyzed in view of the in-medium properties of the P33(1232), the D13)(1520), and the S11(1535) resonances.
