General Comments:

Calculations:

Binding energy, <r2>, multipole moments: 1993Pa04

Level configurations from β decay: 1990So04

Levels: 1979Ha29, 1980Bo07 and 1980Ja16 have searched for high spin isomers in this mass region. For the results of this search, see (HI,xnγ) data set.

Levels: 1980Vr01 have searched for α decay from high spin isomers following (HI,xnγ) reactions with negative results.

Levels: The 19 s α activity with Eα=4460 10 (1971To10) previously assigned to 156Tm high spin decay to the 152Ho high spin isomer is now believed to be a misassignment. This activity was not observed in: 1) 148Sm(14N,6n) reaction, which should have populated high-spin levels (1980Zo02); 2) in a 156Tm source produced by W(600-MeV p) ms (1992Po14).

Gammas: All γ data are from (HI,xnγ) data set, unless otherwise noted.

E(level): Except for the 160 and 179.4 levels, all values are from (HI,xnγ). Values in that dataset were given relative to the 9+ level at 160 set to zero. Values given here are based on E=160 for that isomer but the uncertainty is not included. To get the absolute uncertainty for the excitation energies from this reaction, an additional uncertainty of 1~keV should be included

Jπ(level): For the levels above 200~keV, the assignments are from (HI,xnγ). assignments for levels up to 3020 are from 1994An13. The strong assignments are based on γ mults and excitation functions. The assignments in parens are probable values based on the linking transitions and a comparison with levels in adjacent nuclides. assignments for higher levels are from 1997Ri02 based on angular distributions and DCO ratios. For these levels, the evaluator has added arguments based on mults determined by 1994An13

T1/2(level): From (HI,xnγ), unless otherwise noted
