191PB c 2010Co13: Source produced by bombarding UCx target (50 g/cm{+2}) with
191PB2c the proton pulsed beam. Nuclei produced in the spallation reaction
191PB3c diffused, effused to the high-temperature RILIS ion source cavity.
191PB4c Polonium atoms were irradiated with three different laser beams
191PB5c and extracted from the ion source cavity, accelerated
191PB6c by dc electrical fields to an energy of 50 keV and mass separated in
191PB7c the ISOLDE separator. In Run I, a single Si detector in Run II,
191PB8c two Si detectors (FWHM = 25 keV, 20 keV and 30 keV, respectively for
191PB9c 5500|a), an HPGe detector (FWHM=4.3 keV at E|g=1300 keV). Measured
191PBac E|a, I|a, E|g, |a|g, |g|a, |g|g coin, half-life of {+195}Po, deduced
191PBbc excited levels, spin-parity. Also studied {+191}Bi |e decay.
191PB c 1993Wa04: Source was produced <240-MeV Ne on {+182}W reaction. The
191PB2c mass-separated beam was implanted in aluminized mylar tape. Silicon
191PB3c surface-barrier detectors and silicon PIPS-type (Passivated Implanted
191PB4c Planar Silicon) detectors with energy resolution between 11-20 keV for
191PB5c the 5486|a of {+241}Am. Measured E|a, I|a, half-life of {+195}Po.
191PB c 1967Si09: Source was produced from the {+185}Re({+19}F,X) reaction.
191PB2c Measured E|a, {+195}Po half-life.
