190PB c  1993Wa04 (also 1994Wa13,1989De18): {+194}Po source was produced in the
190PB2c  reaction of 240 MeV Ne beam on {+182}W target at the Leuven Isotope
190PB3c  Separator On-Line (LISOL) facility. Measured E|a, I|a, half-life of
190PB4c  {+194}Po decay

190PB cA IA$Intensities per 100 |a decays are deduced from
190PB2cA I|a(6843)/I|a(6194|a)=93/0.22 measured by 1994Wa13 (also 1995Bi12),
190PB3cA and from the expectation of I|a=0.05 {I5} (<0.10), obtained from
190PB4cA HF(unobserved 6085|a)>1. The uncertainties in I|a values are obtained
190PB5cA from the uncertainty calculated by 1994Wa13 for HF(6194|a).

190PB3cA (1967Si09) and 6846 {I7} (1967Tr06; energy is increased by 1 keV due
190PB4cA to a change in calibration energy, as recommended by 1991Ry01).
190PB5cA Q(|a)({+194}Po)=6987 {I3} yields E|a=6843 {I3}. See also 2002Va13
