Cet article décrit une méthode simple permettant d'adapter l'approximation relativiste de Hartree-Fock à des configurations comprenant des couches incomplètes. Une couche de nombre quantique angulaire / se sépare par effet relativiste en deux sous-couches pour lesquelles j = l + 1/2 et j = l - 1/2, et les électrons peuvent se distribuer de plusieurs façons différentes entre ces sous-couches, donnant ainsi naissance à plusieurs configurations différentes, ayant des énergies presque égales. On étend la notion de moyenne de configuration et l'on donne une moyenne pondérée de tous les termes apparaissant dans ces configurations. Les fonctions d'ondes de Hartree-Fock sont alors déterminées pour cette configuration moyenne ; la ...
