Abstract ： A specific detection system devoted to the detection of weak γ-activities from neutron-rich isotopes in an element-separated source was developed, and successfully used in a new determination of the half-life of the recently identified heavy neutron-rich nuclide 208 Hg. This newly measured half-life is 41+5 -4 min, in agreement with the earlier one of 42+23 -11 min obtained by radiochemical milking method, but experimental precision was improved.
