Long-range dispersion interactions. I. Formalism for two heteronuclear atoms

Research output: Contribution to journal › Article › peer-review

Abstract

A general procedure for systematically evaluating the long-range dispersion interaction between two heteronuclear atoms in arbitrary states is outlined. The C6 dispersion parameter can always be written in terms of sum rules involving oscillator strengths only and formulas for a number of symmetry cases are given. The dispersion coefficients for excited alkali-metal atoms interacting with the ground-state H and He are tabulated. � 2007 The American Physical Society.
