198PB c  T{-1/2}({+202}Po)=44.6 min {I4} was from weighted average of
198PB2c  44.7 min {I5} (1993Wa04), 45.0 min {I15} (1971Ho01,1965Ti03),
198PB3c  43.7 min {I13} (1970DaZM). Others: 44 min (1965Br17).
198PB c
198PB c  |a branching of 1.92% {I7} adopted here is based on parent-daughter
198PB2c  (E|a{-1}({+206}Rn)-E|a{-2}({+202}Po)) correlations and their ratio
198PB3c  of |a intensities (1993Wa04). Others: 2.2% {I3} (1971Ho01),
198PB4c  2.0% {I2} (1967Le21), 2% (1965Br17).

198PB cA HF        r{-0}({+198}Pb)=1.4719 {I20} is calculated from
198PBxcA HF(5588.1|a)=1.0.

198PB cA E         5587.2 {I14} is recommended in 1991Ry01 from the measured
198PB2cA values (energies are adjusted for changes in calibration energies, as
198PB3cA suggested by 1991Ry01): 5583 {I10} (1963Ho18), 5587 {I5} (1967Ti04),
198PB4cA 5579 {I5} (1967Tr06), 5588 {I2} (1968Go12), 5590 {I5} (1970Jo26) and
198PB5cA 5589 {I3} (1970Ra14).
198PB6cA From the
198PB7cA recommended Q(|a) of 5701.1 {I17} E|a=5588.1 {I17} is calculated.
198PB cA IA        only one |a group has been observed. Upper limits on
198PB2cA intensities for unobserved |a transitions to the 2+, 1063.5-keV
198PB3cA level and to the 0+, 1392.1-keV level are obtained by requiring their
198PB3cA hindrance factors to be greater than 1: I|a(4545.7|a to 2+
198PB4cA state)<8|*10{+-5}, I|a(4223.6|a to 0+)<4|*10{+-7} per 100 |a decays.
