A note on the theory of interatomic long‐range forces

Abstract: AbstractsA comment is made on the multipolar expansion formula of the long-range force between hydrogen atoms previously obtained. The second-order perturbation energy neglecting exchange in the framework of the Unsold approximation is evaluated exactly. An extension is made to helium atoms, and to other s-electron interactions. An approximate method is suggested to estimate the interatomic force between two atoms in general.On fait un commentaire sur un dtveloppement multipolaire de la force A longue portee e… Show more

“…In this expression only a part corresponding to the first-order perturbation theory can be evaluated using the formula derived by Fukui and Yamabe [14] and applied by Gordon and Kim [2] for atomic pairs. The calculation of the remaining part can be performed using the method similar to that applied by several authors in the calculations for atom-molecule and molecule-molecule pairs [15].…”
