Abstract
1529391 Producing selective excitation by means of electromagnetic radiation. WESTERN ELECTRIC CO Inc 2 Jan 1976 [2 Jan 1975] 00003/76 Heading G6P In a method of separating different isotopes in which a vapour containing a mixture of the isotopes is irradiated to excite one isotope to an elevated vibrational state and to raise the excited isotope to an electronically elevated level in which electronic charges are separated, the vapour provides a substantially saturated atmosphere which is a non-solvent for any isotope not in the charge-separated form so that the separated charges form nucleation sites at which the condensable vapour fraction condenses. The charge-separation level may be the ionization level or an excited state dipole level. As described a radiation source 1, e.g. a mode-locked neodynium-YAG laser, affords a beam from which two components are derived: a direct component to an irradiation cell 14 and an indirect component, passing through elements 9, 11 to the cell 14. These components, produced by a mirror 8, result from the single laser output beam which has received treatment e.g. filtering, energy downshift, by various optical elements, e.g. element 7. The elements 9, 11 are crystals of, respectively, potassium – dihydrogen – phosphate (KDP) and ammonium – dihydrogen – phosphate (ADP), to produce various harmonics of the laser beam. The irradiation cell 14 contains the isotope mixture vapour and a vapour component of a hydrocarbon (e.g. light machine oil) formed by heating hydrocarbon liquid 17. In a modification, the charge-separated state is achieved by radiation from an UV second laser. Examples illustrate separation of chlorine and uranium isotopes, but other isotopes which can be separated are tabulated.
