Phys. Rev. A 57, 4994–4997 (1998)General formulation of the semirelativistic approach to atomic sum rulesReceived 3 November 1997; revised 16 January 1998; published in the issue dated June 1998 A general scheme is presented for obtaining systematic relativistic corrections to quantum-mechanical sum rules for various calculations in atomic physics. The single-particle picture and the Foldy-Wouthuysen transformation [Phys. Rev. 78, 29 (1950)] are adopted to derive such corrections. Results are obtained for the “generalized Bethe sums,” which include all higher moments of the energy transfer, and explicit results are given to the lowest order of relativistic corrections. © 1998 The American Physical Society URL:
