Abstract：
With an on-line, gas-thermochromatographic Hg element separation as well as a special detection technique, the independent cross sections of the radioactive Hg-isotopes produced from a 600MeV ¹⁸O +^natPb(thick target) reaction system were determined. The independent cross sections of 22 Hg-isotope nuclides in the mass range from ¹⁸⁰Hg to ²⁰⁹Hg were measured. The experimental set-up, the detection technique, the γ-spectrum analyses and the extraction method of production cross sections based on the γ activities from the successively decaying daughter nuclei were described.
