Uranium isotope separation and compound used in this process
Description
This invention concerns a compound formed of a molecule containing the ion uranyl, and a process for separating the isotopes from the uranium that utilizes compounds of this type. This uranium compound is irradiated at a wave length of 810 to 1116 cm-1 to form a selectively excited portion of the uranium compound which is enriched with one of the uranium isotopes and the enriched portion is separated. The preparation stage of the uranium compound consists in vaporizing this uranyl compound containing not less than two uranium isotopes so that this compound is in the vapour phase at a vapour pressure of not less than about 0.1 mm of mercury

La presente invention concerne un compose forme d'une molecule renfermant l'ion uranyle et un procede de separation des isotopes de l'uranium qui utilise des composes de ce type. On irradie ce compose d'uranium a une longueur d'onde de 810 a 1116 cm-1 pour former une portion selectivement excitee du compose d'uranium qui est enrichie en l'un des isotopes d'uranium et on separe la portion enrichie. L'etape de preparation du compose d'uranium consiste a vaporiser ce compose d'uranyle renfermant au moins deux isotopes d'uranium de maniere que ce compose soit en phase vapeur a une tension de vapeur d'au moins environ 0,1 mm de mercureAdditional details
