摘要: A method and apparatus for enrichment of heavy oxygen isotopes is provided wherein an oxygen starting material which contains heavy oxygen isotopes is enriched in at least one of oxygen molecule 16O17O, 16O18O, 17O17O, 17O18O and 18O18O, by means of cryogenic distillation of the oxygen starting material containing heavy oxygen isotopes. In addition, a method and apparatus are provided for further increasing the concentration of at least one of the heavy isotope oxygen molecules by means of conducting isotope scrambling on the above-mentioned plurality of oxygen molecules enriched by means of the above mentioned cryogenic distillation.
