198PO2cA (1995Le04) and 6641 {I1} (1996Ta18; the energy uncertainty is
198PO3cA statistical only). E|a=6637 {I3} was recommended by 1991Ry01 from
198PO4cA earlier measurements. E|a=6639.6 {I18} is calculated from Q(|a)=6773.7

198PO cA E         This |a transition was not observed; its energy is

198PO cA IA        Absolute |a intensity was measured by 1994Wa13, and the
198PO2cA ratio is listed: I|a(6639.5|a)/I|a(5841|a)=(80-100)/(0.0014-0.0018).
198PO3cA In 1995Bi17, this intensity ratio is quoted as 100/0.0018 {I6},
