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