  • Apparatus for extraction and separation of a preferentially photo-dissociated molecular isotope into positive and negative ions by means of an electric field
    Patent number: 4085332
    Abstract: Apparatus for the separation and extraction of molecular isotopes. Molecules of one and the same isotope are preferentially photo-dissociated by a laser and an ultra-violet source, or by multi-photon absorption of laser radiation. The resultant ions are confined with a magnetic field, moved in opposite directions by an electric field, extracted from the photo-dissociation region by means of screening and accelerating grids, and collected in ducts.
