Independent Yield Measurement for the Hg-Isotope Products From 600 MeV 18O+natPb(thick target) System (Ⅰ) Experiment and Technique

  • 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.

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.
