| Abstract: | A new formula is derived for the coefficient D 7 of the leading term in R -7 for the electric dipole moment of two atoms in S-states at a large distance R apart. An approximation is proposed which leads to a simple formula for D 7 involving mainly accessible atomic properties. The approximation is checked for scaled hydrogen atoms and is accurate to about one per cent. |
