Abstract

Separation of gaseous isotopes such as UF.sub.6 by adiabatically expanding a gas stream containing the isotopes to cool to a temperature at which condensation or dimers are formed. Selectively exciting by electromagnetic radiation one isotope compound to inhibit condensation or to effect dissociation of dimers containing one isotope compound. Deflecting the flow of the gas stream to effect a change of isotope distribution in the gas stream. Separating by peeling the enriched portion of the gas stream from the remainder depleted portion of the gas stream.
