Abstract
It is well known1 that a key requirement for an efficient chemical-reaction-based laser isotope separation scheme is that the reaction be photochemical and not thermal in nature. Intracavity experiments were, therefore, carried out with a line-tunable 5.3-μm CO laser to assess the basic chemistry of the UF6 + HCI reaction. This reaction is one of the candidate systems for the photochemical laser isotope separation of uranium.2·3 The CO laser was operated on one of several grating-tunable lines that coincide with the 3v3 absorption band of UF6 with an intracavity power for each line of the order of 20 W. The UF6 disappearace rate was monitored with a HgCdTe detector and a 16-μm narrowband filter which observed the absorption intensity of a focused and chopped IR globar beam. The globar beam crossed the laser beam and intracavity cell axis at right angles.
