182HG2cN (1997Ba25), 50 {I25} (1997An09). 1972Ga27 and 1974Le02 report %|a=5
182HG3cN and 2.4, respectively, but T{-1/2} in each of these studies
182HG4cN differs from the adopted value. Only the |a decay of {+186}Pb has been
182HG6cN observed and the %|a branch has been measured from |a-|a correlations.
182HG7cN The |b decay of {+186}Pb has not been studied, and |a/|b branchings
182HG8cN have not been determined experimentally.

182HG cA E$measured energies are 6337 {I15} (1997Ba25), 6320 {I15} (1997An09),
182HG2cA 6331 (1980Sc09), 6319 {I20} (1974Le02), 6335 {I10} (1984To09) and
182HG3cA 6320 {I10} (1972Ga27). The E|a values given by 1974Le02 and 1980Sc09
182HG4cA are adjusted for calibration as recommended by 1991Ry01.
182HG5cA Q(|a)({+186}Pb)=6470 {I6} (2012Wa38) yields E|a=6331 {I6}. E|a=6328
182HGxcA {I6} is recommended in 1991Ry01.

182HG cA E$this |a transition has not been observed; its energy
182HG2cA is calculated from E(level)=351.8 {I3} and Q(|a)=6470 {I6}.
182HG cA IA$1994Wa23 calculate HF for this |a branch
182HG2cA (the |a hindrance factors were calculated by using the Rasmussen
182HG3cA formalism from their experimental upper limit for I|a). Their hindrance
182HG4cA factor corresponds to I|a(5988|a)<0.16 per 100 |a decays.
182HG cA $An upper limit of 3.6 per 100 |a decays is deduced for an
182HG2cA |a transition to the 2+ state by requiring its hindrance factor
182HG3cA to be greater than 1.
