Abstract
Separation of isotopes from a mixture of respective compounds particularly UF.sub.6 compounds, containing the respective isotopes, physically or chemically by means of laser radiation, by passing through a vaporous mixture of the compounds, laser radiation having a spectral width maximally corresponding to the width of the isotope shift, the frequency being adjusted so that points of accumulation of rotational vibration lines of the one compound containing the desired isotope are covered in the spectrum, and the intensity of the radiation is so high that its absorption reaches the saturation region. With a pulsed laser, the duration of the radiation is shorter than the rotational relaxation time. With a continuously radiating laser, the intensity of the radiation is so high that the chemical or physical separation process is faster than the rotational relaxation.
