Abstract
A method of concentrating the stable oxygen isotopes ofO andO by irradiating ozone with light, selectively dissociating an isotopologue of ozone containing an oxygen isotope in its molecule into oxygen, followed by dissociating the ozone and separating the formed oxygen from the non-dissociated ozone. In the ozone photodissociation step, light is radiated onto a rare gas-ozone mixed gas containing ozone and at least one rare gas selected from krypton, xenon and radon is used to selectively dissociate ozone containing a specific oxygen isotope in its molecule into oxygen then the oxygen isotope is separated from non-dissociated ozone and rare gas to concentrate the oxygen isotope present in the separated oxygen.
