198Pt can decay by double β- decay to 198Hg. Upper limits on 198Pt half-life have been measured. For details, see T1/2 comment for g.s. of 198Pt in Adopted Levels for 198Pt
Levels: For band configurations, see 1985Ko13, 1984Go06, 1977Gu05, 1974Pr13, and 1974Ya03.
Gammas: For unplaced γ’s, see 198Tl ε decay (5.3 h), 198Tl ε decay (1.87 h) and 196Pt(α,2nγ).
