| Abstract: | 128Xe is produced by one-day irradiation of potassium iodide at a neutron flux of 1013 n·cm−2·s−1 at a rate of 0.9 mm3 TPN for one gram of iodine. Xe is separated from the matrix by melting or hydrolysis. The main part of water is removed from
the gas by cooling. Xenon (∼99%) thus obtained is freed from H2, O2, N2, CH4 and the last traces of water by gas chromatography and used for isotopic analysis.
