ABSTRACT:
A gaseous mixture containing elementary particles (atoms or molecules) of first and second isotopes is exposed to laser radiation at a predetermined frequency to excite elementary particles of the first isotope without substantially exciting elementary particles of the second isotope. An electric discharge is established in the gaseous mixture to produce preferential ionization of elementary particles of the first isotope. Electrophoresis in the discharge (either cataphoresis or the formation of a plasma sheath at the lateral extremity of the discharge) causes preferential migration of elementary particles of the first isotope to a first location and preferential migration of elementary particles of the second isotope to a second location. Portions of the gaseous mixture enriched in the first and second isotopes, respectively, are removed from the respective first and second locations.
