Abstract

On a exploré différents moyens d'obtenir la polarisabilité d'un atome ou d'une molécule dont on a la fonction d'onde en méthode S.C.F. L.C.G.O. M.O. Le comportement expérimental du tenseur de polarisabilité de l'association Ar-Ar en fonction de la distance interatomique est assez correctement reproduit par les calculs les plus élaborés que nous ayons faits, lesquels restent dans le cadre de l'approximation Hartree-Fock.

Different ways of obtaining the polarizability of an atom or a molecule from its S.C.F. L.C.G.O. M.O. wave-function have been investigated. The experimental behaviour of the polarizability tensor of the Ar-Ar association according to the interatomic distance is correctly reproduced by our most accurate calculations which remain within the framework of the Hartree-Fock approximation.
