ABSTRACT:
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 ozonizer12into a distillation column13filled 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 cell14, 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.
