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 <Gamma>-activities of the neutron-rich Hg isotopes. The half-life of ²⁰⁹Hg was determined to be 35_-6⁺⁹ s.
