Abstract

Two new neutron-rich rare-earth isotopes [Formula Presented] and [Formula Presented] produced in the proton-induced fission of [Formula Presented] were identified using the JAERI on-line isotope separator (JAERI-ISOL) coupled to a gas-jet transport system. The half-lives were determined to be 4.8±0.8 s for [Formula Presented] and 10.3±1.6 s for [Formula Presented] The assignment of these isotopes was based upon the observation of Eu and Tb K x rays in the [Formula Presented]-gated x/[Formula Presented]-ray spectra measured for the separated mass fraction 177 and 181 as monoxide ions [Formula Presented] and [Formula Presented] respectively.
