A method for separating isotopes through selective excitation
Description
The invention relates to the isotopic separation methods. It refers to a method according to which a gaseous compound of an element, the isotopes of which have to be separated, is irradiated by infra-red radiations so that it absorbs several quanta of infra-red radiations and thus reaches a highly excited state, the excited molecules subsequently receiving visible or U.V. quanta leading them to an excited electronic state, in which excited and non excited molecules can be separated, e.g. by chemical reaction. This can be applied to the separation of isotopes 235 and 238 of uranium
Abstract (French)
L'invention concerne les procedes de separation isotopique. Elle se rapporte a un procede selon lequel un compose gazeux d'un element dont les isotopes doivent etre separes est irradie par un rayonnement infrarouge et atteint ainsi un etat vibrationnel excite eleve, les molecules excitees recevant ensuite des quantums visibles ou ultraviolets qui les portent dans un etat electronique excite dans lequel les molecules excitees et non excitees peuvent etre separees, par exemple par reaction chimique. Ceci est applicable a la separation des isotopes 235 et 238 de l'uraniumAdditional details
