194PB c  1993Wa04, 1994Wa13: samples of {+198}Po were produced at the Leuven
194PB2c  Isotope Separator On-Line (LISOL) facility in Belgium. |a particles
194PB3c  were detected with a PIPS detector (FWHM=15 keV). Measured E|a, I|a,
194PB4c  decay curve. Deduced parent T{-1/2}, |a-decay branching ratio.
194PB c  1982Bo04: samples of {+198}Po were produced via (p,X) with E=5 GeV
194PB2c  proton beam from the LBL Bevatron. |a particles were detected with
194PB3c  gold-plated silicon surface-barrier detectors. Measured E|a, I|a,
194PB4c  decay curve. Deduced parent T{-1/2}.
194PB c  1971Ho01: {+198}Po samples were produced in ISOLDE facility via (p,X)
194PB2c  with E=600 MeV proton beam from the CERN synchro-cyclotron. |a
194PB3c  particles were detected with silicon surface-barrier detectors.
194PB4c  Measured E|a, I|g, decay curve. Deduced parent T{-1/2}, |a-decay
194PB5c  branching ratio.

194PB cA IA$|a intensity per 100 |a decays. No |a transition
194PB2cA (5236-keV) to the 2+ state at 965.0 keV has been observed.
194PB3cA Its intensity is calculated as <0.0027 per 100 |a decays by assuming
194PB4cA HF(unobserved 5236|a)>1.
