2008Os02: 166Eu identified and produced in 238U(p,F) reaction at E(p)=36 MeV. Target=600-800 mg/cm2 natural UCx containing 1 g/cm2 238UCx. Experiments carried at JAEA on-line isotope separator (JAEA-ISOL) and ISOL-based Tokai radioactive ion accelerator complex (TRIAC) using newly developed forced electron beam induced arc discharge (FEBIAD-β2) type ion source, and a surface ionization type ion source. Mass separation of the fission products was achieved by an integrated target-ion source system connected to the acceleration chamber of the mass separator. The activities were deposited on a tape transport system. Measured Eγ, βγ-coin, β(x ray)-coin, half-life
