Abstract： The β- decaying γ scheme of the neutron-rich nuclide 208Hg has been determined for the first time. The 208Hg was produced in multi-nucleon transfer reaction taking place in the bombardment of 18O-beam on natural lead target, and the Hg-element products were separated with a gas-thermochromatography technique. The γ-ray single and γ-γ coincident spectra were measured. A partial 208Hg γ scheme was proposed. Twenty-six γ rays were assigned to follow the β- decay of 208Hg. At the same time, a new level structure of the daughter nucleus 208Tl was constructed, in which three new levels at 1.72 MeV, 1.652 MeV, and 1.362 MeV were affirmed. The experimental 208Tl level structure was compared with a shell-model calculation.
