Abstract
This paper describes in detail the procedures used in the identificati on of the new neutron-rich isotope Hg-208 and the measurement of its h alf-life, The identification included two step chemical separations, T he first step was the collection of Hg element products from the irrad iated target with high efficiency and good element selectivity, which was realized by means of an off-line melt Pb target device, The second step was to extract periodically the growing Tl element from the coll ected Hg sample, In the gamma spectra of the extracted Tl sample, a 26 14.6 keV activity with a half-life of 3 minutes was observed, which ma y only be assigned to the daughter Tl-208 of Hg-208 beta(-) decay,
