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 mercury isotopes produced by 600MeV 18O+(thick target) reaction. A special detection method was used to detect the - delayed rays from neutron-rich mercury isotopes. The half-life of ²⁰⁹Hg was determined to be 35+9－6s.
