Abstract

A new neutron-rich isotope 166Tb produced in 16 MeV proton-induced fission of 238U has been identified using the JAERI on-line isotope separator (JAERI-ISOL) coupled to a gas-jet transport system. Dy KX-rays arid γ rays originating from the decay of 166Tb were found in. both mass-166 and 182 fractions, where the 166Tb nuclides were mass-separated as elemental ions 166Tb+ and monoxide ions 166TbO+, respectively. The half-life of 166Tb has been determined as 21 ±6 s, which is much shorter than theoretical predictions. A decay scheme of 166Tb has been proposed and a probable spin assignment for the 166Tb ground state has been discussed.
