Energy-weighted sum rules for spin operators

Energy-weighted sum rules are obtained for the spin part, both isocalar and isovector, of the magnetic dipole operator. The same interaction is used to evaluate the relevant double commutator as is sed to induce ground-state correlations. First a spin-dependent delta interaction is used; then a tensor interaction is considered. The main point of this work is that there is a lot of energy-weighted strength at high energies. (orig.)
