E(level) (keV) | XREF | Jπ(level) | T1/2(level) |
0.0 | AB | (1-) | 45.9 m 2 % β- = 100 |
E(level): The γ’s, which are all unplaced, are not given here; see 158Sm β- decay.
E(level): Levels have been proposed in an unpublished study of the decay of 158Sm and used in the analysis of the total absorption γ spectrum (1997Gr09), but have not been adopted.
