Abstract
L'INVENTION CONCERNE LA SEPARATION ISOTOPIQUE. POUR AMELIORER LE RENDEMENT D'UN PROCEDE DE SEPARATION ISOTOPIQUE PAR PHOTO-EXCITATION, ON REALISE UN BALAYAGE DES FREQUENCES D'EXCITATION DEFINIES PAR UN ENSEMBLE DE RAIES DE MODE 46, AFIN QUE CHACUNE DE CES RAIES COINCIDE EXACTEMENT PENDANT UN INSTANT AVEC L'UNE DES RAIES 40 QUI CONSTITUENT LA STRUCTURE HYPERFINE DU SPECTRE D'ABSORPTION DE L'ISOTOPE QUE L'ON DESIRE EXCITER SELECTIVEMENT. APPLICATION A L'ENRICHISSEMENT DE L'URANIUM.
