| Résumé : | The formalism of non-equilibrium quantum statistical mechanics developed by R. Balescu provides a convenient framework for deriving kinetic equations. It requires the definition of concepts such as vacuum of correlation and free motion operator. We propose a realization of such concepts for bound states in the concrete case of quantum gases starting from a description in terms of electrons and nuclei. Polarized hydrogen and unpolarized helium gases are considered. © 1989. |
