Description

A search for unknown neutron-rich rare-earth isotopes and neutron-deficient americium isotopes was carried out using a gas-jet coupled thermal ion source installed in the JAERI on-line isotope separator (JAERI-ISOL). New isotopes 166Tb and 165Gd produced in the proton-induced fission of 238U were identified. The half-lives were 21±6 s for 166Tb and 10.3±1.6 s for 165Gd. Pu KX-rays associated with EC decays of americium isotopes produced in heavy-ion induced reactions were observed in the X/γ-ray spectra for the mass separated fraction of 237 and 236. (orig.)
