Supersymmetric sum rules for electromagnetic multipoles

We derive model-independent, nonperturbative supersymmetric sum rules for the magnetic and electric multipole moments of any theory with N=1 supersymmetry. We find that in any irreducible N=1 supermultiplet the diagonal matrix elements of the {ital l}-multipole moments are completely fixed in terms of their off-diagonal matrix elements and the diagonal (l{minus}1)-multipole moments. {copyright} {ital 1998} {ital The American Physical Society}
