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.
