    Abstract: (U.S. 37,877) A method for the separation of isotopes is disclosed including providing a vapor of a compound of the element whose isotopes are to be separated, the compound having an isotopically shifted but overlapping infrared absorption spectrum associated with the isotopes of that element within a predetermined temperature range, irradiating the vapor with a predetermined fluence of infrared radiation which is preferentially absorbed by a molecular vibration of the molecules of the compound containing a predetermined isotope of the element, thereby providing excited molecules enriched in the predetermined isotope, while maintaining the vapor at a temperature within the predetermined temperature range which, at thermal equilibrium, provides sufficient molecules requiring more than a single photon to promote dissociation so that upon dissociation the isotopic selectivity is at least ten percent above the maximum selectivity which can be achieved with an ensemble of molecules, each of which can dissociate by absorbing a single photon. In a preferred embodiment, the isotopes of uranium are separated utilizing uranyl compounds having the formula UO2A2.L where A is a monovalent anion and L is a neutral ligand having a basicity towards the uranyl ion equal to or stronger than that of tetrahydrofuran (THF).

    Abstract: The instant invention relates to a process for separating a material into two or more parts in each of which the abundances of the isotopes of a given element differ from the abundances of the isotopes of the same element in said material. More particularly, the invention relates to a method for the isotopically selective excitation of gas phase molecules by infrared radiation and the conversion of these molecules either by the same radiation or by an excited state chemical reaction to form a product which may be separated by means known in the art. The instant invention is useful for but not limited to the separation of the principal isotopes of uranium.

    Abstract: The instant invention relates to a process for separating a material into two or more parts in each of which the abundances of the isotopes of a given element differ from the abundances of the isotopes of the same material in said material. More particularly, the invention relates to a method for the isotopically selective excitation of gas phase UF6 by infrared photon absorption followed by selective reaction of said excited UF6 with atomic chlorine, bromine, or iodine to form a product which may be separated by means known in the art.

    Abstract: The present invention concerns an unique laser radiometer capable of accurately measuring the radiation temperature of a radiant surface and independently measuring the surface's emissivity. A narrow-band radiometer is combined with a laser reflectometer to measure concurrently radiance and emissivity of a remote, hot surface. Together, radiance and emissivity yield the true surface temperature of the remote target. A narrow receiver bandwidth is attained by one of two methods; (a) heterodyne detection or (b) optical filtering. A direct measurement of emissivity is used to adjust the value obtained for the thermal radiation signal to substantially enhance the accuracy of the temperature measurement for a given subject surface. The technique provides substantially high detection sensitivity over a very narrow spectral bandwidth.
