Data for excited levels are primarily from the (HI,xnγ) studies.

Levels: Lifetimes for 9 levels above 3500 keV have been measured by 1981Wa04 and 1979Ag01. Since these values are very different and may depend on ordering of the γ rays, and the ordering adopted here is different, the half-lives have not been adopted.

Gammas: The unplaced γ’s are not given here, see (HI,xnγ) data and ¹⁵⁴Tm ε decay (3.3 s).

Q-value: S(2n)=18247 10, S(2p)=7065 6 (2021Wa16)

Q(β-)=-8178 keV 15	S(n)= 10210 keV 10	S(p)= 4882 keV 7	Q(α)= 4279.7 keV 26
