Virial theorem and the Born-Oppenheimer approximation at different orders of perturbation
Description
The link between the virial theorem and the adiabatic approximation is studied for a few orders of perturbation. It is shown that the total energy of the system is distributed between the mean values of kinetic and potential energy of the nuclei and the electrons in each order of perturbation. No static approximation connected with the Hellmann-Feynman theorem is made
Abstract (French)
On etudie le lien entre le theoreme du viriel et l'approximation adiabatique pour plusieurs ordres de perturbation. La repartition de l'energie totale du systeme entre les energies cinetiques et potentielles moyennes des noyaux et des electrons est explicitee pour chaque ordre de perturbation sans faire usage de l'approximation statique mettant en jeu un viriel de forces de Hellmann-FeynmanAdditional details
