Abstract
The instant invention relates to a process for separating a material into two or more parts in each of which the abundances of the isotopes of a given element differ from the abundances of the isotopes of the same material in said material. More particularly, the invention relates to a method for the isotopically selective excitation of gas phase UF.sub.6 by infrared photon absorption followed by selective reaction of said excited UF.sub.6 with atomic chlorine, bromine, or iodine to form a product which may be separated by means known in the art.
