Energy weighted sum rule in Na clusters

Mesoscale and Nanoscale Physics 2011-11-29 v2

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, N{\cal N}. For illustration the formalism was applied to the case of NaNa clusters. One concludes that the RPA results for NaNa clusters obey the modified TRK sum rule.
