An important nuclear physics issue is the question whether the intrinsic properties of free nucleons change inside nuclei. One such property is the strong isovector M1 transition connecting the nucleon with the Δ(1232). It dominates the nuclear electromagnetic response at excitation energies in the range ω = 200 – 400 MeV.
