Transition Densities

An energy-weighted sum rule is written down containing both isoscalar and isovector transition densities. As an application, a previously obtained expression for the isoscalar transition density of a dipole state is rederived.

Special Case

Energy-weighted sum rules with separated isospin contributions for arbitrary operators and multipolarities are developed for photonuclear and electron-scattering transitions. The Kurath sum rule is contained as a special case. Applying the sum rule to magnetic dipole transitions, ensuing numerical predictions for non-self-conjugate nuclei are compared with experimental results.
