摘要：
Recent chiral EFT calculations of nucleon polarizabilities reveal a problem in the current empirical determination of proton's electromagnetic polarizabilities. We also report on the progress in the empirical determination of the Delta(1232)-resonance magnetic moment in the process of gamma p -> p pi(0)gamma' measured at MAMI.
