For a Q{center_dot}Q interaction the energy-weighted sum rule for isovector orbital magnetic dipole transitions is proportional to the difference {summation}B(E2,isoscalar){minus}{summation}B(E2,isovector), not just to {summation}B(E2,physical). This fact is important in ensuring that one gets the correct limit as one goes to nuclei, some of which are far from stability, for which one shell (neutron or proton) is closed. {copyright} {ital 1997} {ital The American Physical Society}
