Method for isotope enrichment of mercury-196 by selective photoionization

Patent Paisner, J.A.; Crane, J.K.

This patent describes a method for selectively photoionizing /sup 196/Hg atoms in a vapor comprising the naturally-occurring distribution of mercury isotopes, comprising the steps of: subjecting the vapor to radiation emitted by a first radiation source at a first determined wavelength of 2537 A; subjecting the vapor to radiation emitted by a second radiation source at a second wavelength of 2655 A; and subjecting the vapor to radiation emitted by a third radiation source at a third wavelength of less than about 1.40 microns whereby the additive effect of the sources upon the vapor selectively ionizes /sup 196/Hg atoms.

Method of controlling the mercury vapor pressure in a photo-chemical lamp or vapor filter used for Hg.sup.196 enrichment

Patent Grossman, Mark W. (Belmont, MA)

The present invention is directed to a method of eliminating the cold spot zones presently used on Hg.sup.196 isotope separation lamps and filters by the use of a mercury amalgams, preferably mercury - indium amalgams. The use of an amalgam affords optimization of the mercury density in the lamp and filter of a mercury enrichment reactor, particularly multilamp enrichment reactors. Moreover, the use of an amalgam in such lamps and/or filters affords the ability to control the spectral line width of radiation emitted from lamps, a requirement for mercury enrichment.

Method for isotope enrichment by photoinduced chemiionization

Patent Dubrin, James W. (Walnut Creek, CA)

Isotope enrichment, particularly .sup.235 U enrichment, is achieved by irradiating an isotopically mixed vapor feed with radiant energy at a wavelength or wavelengths chosen to selectively excite the species containing a desired isotope to a predetermined energy level. The vapor feed if simultaneously reacted with an atomic or molecular reactant species capable of preferentially transforming the excited species into an ionic product by a chemiionization reaction. The ionic product, enriched in the desired isotope, is electrostatically or electromagnetically extracted from the reaction system.

Method for laser induced isotope enrichment

Patent Pronko, Peter P.; Vanrompay, Paul A.; Zhang, Zhiyu

Methods for separating isotopes or chemical species of an element and causing enrichment of a desired isotope or chemical species of an element utilizing laser ablation plasmas to modify or fabricate a material containing such isotopes or chemical species are provided. This invention may be used for a wide variety of materials which contain elements having different isotopes or chemical species.
