 86Y  c  {+86}Y isomer also decays by |e decay.
 86Y  c  2010Ru07: measured half-life from decay curve of 218|g
 86Y  c  1962Ki04: {+86}Y produced through the {+85}Rb(|a,3n) and {+86}Sr(d,2n)
 86Y 2c  reactions. Gammas were measured using one NaI(Tl) scintillator and the
 86Y 3c  conversion electrons were examined using magnetic spectrometers.
 86Y  c  1972Si11: The isomeric state in {+86}Y was excited through the
 86Y 2c  {+87}Sr(p,2n) reaction at 24 MeV on enriched targets. Measured E|g and
 86Y 3c  |g|g coin. using an x-ray spectrometer and a Ge(Li) detector.
