Abstract:
The new neutron-rich nuclide 209Hg has been identified for the first time. An on-line, gas-thermochromatographic technique was developed for rapidly separating the Hg-element products from 600-MeV 18O+natPb(thick target) reaction system. A special detection arrangement was used in order to detect the weak γ-activities of the neutron-rich Hg isotopes. The half-life of 209Hg was determined to be 35−6 +9 s.
