“…At low energies the relative strengths of electromagnetic multipoles were analyzed [13,16,19,25,33,64,95,169] for comparison with predictions from multipole sum rules. The interesting question, whether the electromagnetic polarizabilities of the nucleon inside the nucleus essentially differ from those of the free nucleon, has been theoretically addressed [80,82,104,166,168] and experimentally studied with good accuracy [39,43,48,170].…”
