Abstract
L'invention a pour objet un procédé pour exciter et séparer sélectivement un isotope ou une molécule choisi présent dans un mélange d'isotopes ou de molécules. Selon ce procédé, on porte le mélange d'isotopes à un état gazeux excité, après quoi on désexcite sélectivement un ou plusieurs isotopes du mélange, puis on le ou les sépare de façon permanente des isotopes excités. Application à la séparation des isotopes de l'uranium et de métaux lourds.
