ABSTRACT:
A desired isotope mixed with one or more other isotopes is selectively excited by laser radiation absorbed by only that isotope, so that that one isotope selectively enters into a chemical reaction with a reaction partner fed to the mixture. The desired selectivity can be degraded here by thermally activated reactions between the other isotopes and the partner. To avoid this effect, the mixture and partner in the necessary reaction vessel are irradiated for one or more short time intervals after each of which the vessel's content is adiabatically emptied into a vacuum vessel. Each time interval may be made short enough to avoid the thermal activation.
