Abstract
L'INVENTION A TRAIT A LA SEPARATION DES ISOTOPES. LE PROCEDE DE L'INVENTION CONSISTE A PRODUIRE UNE VAPEUR D'UN COMPOSE DE L'ELEMENT DONT LES ISOTOPES DOIVENT ETRE SEPARES ET A IRRADIER CETTE VAPEUR AVEC UNE FLUENCE PREDETERMINEE DE RAYONNEMENT INFRAROUGE DE MANIERE A PRODUIRE DES MOLECULES EXCITEES ENRICHIES EN L'ISOTOPE RECHERCHE, TOUT EN MAINTENANT LA VAPEUR A UNE TEMPERATURE QUI, A L'EQUILIBRE THERMIQUE, DONNE UN NOMBRE SUFFISANT DE MOLECULES NECESSITANT PLUS D'UN SEUL PHOTON POUR FAVORISER LA DISSOCIATION DE MANIERE QUE LA SELECTIVITE ISOTOPIQUE SOIT SUPERIEURE D'AU MOINS 10 AU MAXIMUM POUVANT ETRE OBTENU AVEC UN ENSEMBLE DE MOLECULES, DONT CHACUNE PEUT SE DISSOCIER PAR ABSORPTION D'UN UNIQUE PHOTON. APPLICATION A LA SEPARATION DES ISOTOPES DE L'URANIUM.THE INVENTION RELATES TO THE SEPARATION OF ISOTOPES. THE PROCESS OF THE INVENTION CONSISTS OF PRODUCING A VAPOR FROM A COMPOUND OF THE ELEMENT WHOSE ISOTOPES MUST BE SEPARATED AND IN IRRADIING THIS VAPOR WITH A PREDETERMINED FLUENCE OF INFRARED RADIATION SO AS TO PRODUCE EXCITED MOLECULES ENOTRICHED RESEARCHED BY THE ISOTOPES , WHILE MAINTAINING THE VAPOR AT A TEMPERATURE WHICH, AT THERMAL EQUILIBRIUM, GIVES A SUFFICIENT NUMBER OF MOLECULES REQUIRING MORE THAN A SINGLE PHOTON TO PROMOTE DISSOCIATION SO THAT THE ISOTOPIC SELECTIVITY IS GREATER BY AT LEAST 10 THAN 10 TO BE OBTAINED WITH A SET OF MOLECULES, EACH OF WHICH CAN DISSOCIATE BY ABSORPTION OF A SINGLE PHOTON. APPLICATION TO THE SEPARATION OF ISOTOPES OF URANIUM.
