General Comments:

Levels: The adopted level scheme follows mostly the one proposed in 1998Fo02, and is based on Eγ, Iγ, γγ and γγγ coincidences, and DCO (directional correlation) ratios. Other important contributions are the half-life and conversion coefficient measurements from 1999La06. While there is reasonable agreement between 1999La06 and 1998Fo02 about the band based on the 13/2+ isomeric state, as shown in the reaction datasets below, there are significant differences regarding the 15/2+ band. See also the comments preceding the Adopted Gammas table for a discussion about disagreements between both papers regarding many γ-ray intensities. Furthermore, there is a shift in the level energies of 1999La06 with respect to those in common with the level scheme from 1998Fo02, due to a systematic offset of about 0.3 keV in the γ-ray energies reported in both papers (see comment preceding Adopted Gammas table).

Gammas: γ-ray data are mostly from 173Yb(24Mg,6nγ) (1998Fo02). There is reasonable agreement between this source and 180W(16O,5nγ) (1999La06) regarding the γ-ray energies, but there are significant differences with respect to the intensities of γ rays below about 450 keV, reaching a factor 3-4 for the lowest energies (see the corresponding datasets). Note also that there are a few higher energy transitions (577 and 712 keV) which also exhibit an intensity ratio exceeding 3 between both publications. There is also a systematic shift in the γ-ray energies, with those from 1999La06 (which are the more precise values) an average of 0.3 4 keV above the energies reported by 1998Fo02. This difference is of course reflected in the corresponding level energies. All these discrepancies cannot be resolved in the context of the present evaluation, and would require further measurements to clarify the issue.

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

Q-value: Q(β+)=6040 10 keV (2003Au03)

E(level): The level energies are from a least-squares adjustment to the adopted γ-ray energies, and are relative to the (13/2+) isomeric state, except where noted.

E(γ): The tabulated γ-ray energies are either from 1998Fo02 in 173Yb(24Mg,6nγ), or a weighted average from the data in 1998Fo02 and in 180W(16O,5nγ) (1999La06), whenever values from the latter reference were available.

I(γ): Relative photon branching for each level are calculated from relative Iγ of 1998Fo02 in 173Yb(24Mg,6nγ).
