摘要： A method of enriching a heavy oxygen isotope by distillation of the present invention includes: a first distillation step of feeding oxygen and ozone generated by an ozonizer 12 into a distillation column 13 filled with a diluent gas, and separating the oxygen, and the ozone and the diluent gas; a photodecomposition step of introducing a mixed gas of the ozone and the diluent gas from a bottom of the distillation column into a photoreaction cell 14, and irradiating the mixed gas with a laser light to selectively decompose the ozone containing the heavy oxygen isotope; and a second distillation step of returning non-decomposed ozone and oxygen containing the heavy oxygen isotope to the distillation column, and separating the oxygen, and the ozone and the diluent gas.

摘要： A method for isotope separation of ytterbium comprises isotope-selective photoionizing of a target isotope by use of a laser, and photoionizing of the target isotope from a metastable state to a continuum state or an auto-ionization state through excited states. The photoionized isotope ions of ytterbium can be separated within an electric field. With the method, it is possible to separate a great amount of ytterbium isotope by use of a simple apparatus while ensuring a highly economic efficiency in comparison with a conventional EM method.

摘要： A process and apparatus for separating element isotopes in a microgravity or low-gravity environment using electromagnetic radiation, e.g., sunlight, to heat and ionize a stream of raw materials, followed by electromagnetic separation, and collection of the desired isotopes in or on one or more collection surfaces or receptacles, such as a rotating surface. A cylindrical mirror can serve to collect and concentrate the electromagnetic radiation, permitting the stream of material to be heated and ionized while the path of the stream of material is oriented other than parallel to the direction of the radiation.

摘要： Nozzle cooling and wall contact prevention control are included in a gaseous CRISLA apparatus, along with removable collectors, and the efficient use of one or more currently available high power lasers to produce a commercially economic isotope separation process. The wall contact prevention is accomplished with gaseous boundary layers, and a supersonic nozzle normally is used to cool and separate excitation bands of the isotopic material. Non-intermixing gaseous streams with different isotopic assays can be created in a single nozzle chamber and segmented collection chamber, which along with recirculation loops and compressors, allows a single laser system and a single nozzle system to be used to selectively excite the isotopic material while it makes multiple passes through the laser beams of the laser system until only a small fraction of the desired isotope remains to be separated. The process is especially effective in separating .sup.235 UF.sub.6 from a gaseous mixture of .sup.235 UF.sub.6 and .sup.238 UF.sub.6.

摘要： The improved isotope separator comprises a vacuum vessel, a plasma generator located substantially in the center of the vacuum vessel, an electrode bounded by a hyperboloid of one sheet and a pair of electrodes bounded by a hyperboloid of two sheets, said electrodes being located within the vacuum vessel in such a way as to surround the plasma generator, a power source for supplying said electrodes with a fixed voltage and a pulsating voltage, and magnetic field generating means located outside the vacuum vessel. The apparatus is implemented by a method for isotope separation that achieves high separation factor per stage (process), that enables the process throughput to be increased with ease and which yet is applicable to the isotopic separation of many elements.

摘要： A simple system for obtaining high dissociation yield in a single highly selective step, even at very high pumping powers, in the molecular laser isotope separation (MLIS) route of Uranium Hexafluoride (UF.sub.6), is described. In order to selectively excite and dissociate the desired isotope .sup.235 UF.sub.6 two beams with frequencies corresponding to the first and second energy excitation levels of this isotope at .omega..sub.1 =.omega..sub.0 and .omega..sub.2 =.omega..sub.0 +.omega..sub.12 respectively where .omega..sub.12 is the frequency difference between the first and second energy excitation levels, are simultaneously applied to the supercooled Uranium Hexafluoride molecular gas. Special arrangements which involve the perpendicular crossing of two sets of such beams derivable from the same set of collinear beams polarized in the same direction, allow for the supercooled gas to be uniformly illuminated in configurations equivalent to a Mach-Zehnder interferometer with the gas substituted for the position of the reuniting beamsplitter further enhancing the selectivity of the desired isotope. The versatility of the method enables it to be applied to any particular molecular gas with closely spaced isotopes.
