Open the CIPO recordAbstract From the Canadian patent
Method and apparatus for separating isotopes of an element in an atomic or molecular mixture. The isotropic recoil momenta resulting from selective excitation and ionization of an atomic beam is used to mechanically separate a desired isotope from the beam. Similarly the isotropic, recoil momenta resulting from selective photon excitation and promotion of dissociative electron attachment of a molecular beam of uranium hexafluoride is used preparatory to mechanical separation. The isotropic recoil momenta resulting from multi-photon dissociation recoil in a molecular beam of UF6 or SF6 is also used for separation. And matrix formation of UF6 in HBr so as to collapse the .gamma.3 vibrational …
