General Comments:

Theoretical references: 2005Mc08, 1997Es01, 1997De21, 1995Ch01, 1991Ba31

Levels: Levels established from (HI,xnγ) and 178Ir ε decay studies. For discussions regarding band assignments and structures see the individual datasets.

Gammas: Qt values for several transitions have been read by evaluators from the plot in Fig. 5, 2005De48.

Gammas: See Comments column for data and references justifying the adopted multipolarities.

Q-value: Note: Current evaluation has used the following Q record

Q-value: Q(β+)=2110 30 keV (2003Au03)

E(level): From least-squares fit to adopted γ-ray energies.

Jπ(level): Assignments are from (HI,xnγ) based mostly on band structure, γ-ray multipolarities, angular distributions, and γ-ray decay patterns, and on 178Ir ε decay.

E(γ): From average of (HI,xnγ) and 178Ir ε decay data, when both available; else 1982Dr03 HI reaction data, unless otherwise specified.

I(γ): From (HI,xnγ), or from 178Ir ε decay study, when the former did not provide values.
