Abstract

The energy-weighted sum rule for an electric dipole transition operator of a Schiff type differs from the Thomas-Reiche-Kuhn sum rule by several corrective terms which depend on the number of system components, \cal N. For illustration the formalism was applied to the case of Na clusters. One concludes that the RPA results for Na clusters obey the modified TRK sum rule.
