211RA c 2004He25: produced using the {+204}Pb({+12}C,5n) reaction at GSI.
211RA2c Evaporation residues were separated from the primary beam by the
211RA3c velocity filter SHIP and were implanted into a 16-strip PIPS
211RA4c detector. |g-rays were detected in prompt or delayed coincidence
211RA5c using a HP Ge-Detector and a clover detector consisting of four Ge
211RA6c crystals. Measured E|g, I|g, T{-1/2}.
211RA c 2006Ha17: produced in commissioning experiment using
211RA2c {+174}Yb({+40}Ar,3n) reaction. Evaporation residues were transported
211RA3c by the VASSILISSA separator and implanted into a 16-strip
211RA4c position-sensitive Si detector. The focal plane detector is
211RA5c surrounded by a GABRIELA setup of seven Ge detectors, six of which are
211RA6c inside BGO Compton shields. Measured E|g, T{-1/2} using |g-spectra
211RA7c from unsuppressed detector. Authors state their value T{-1/2}=9.7
211RA8c |ms {I6} requires further independent confirmation therefore
211RA9c evaluators have not used it to obtain average values.
211RA cG $Two unplaced |g-lines of 395.6 keV {I5} and 801.2 keV {I5} observed
211RA2cG by 2004Re04 agree with data of 2004He25.
