E(level): From least-squares fit to Eγ’s
Jπ(level): For the levels above 1391 keV, the listed Jπ values are those in 1982Sc03 and are based on the measured reduced transition probabilities of the primary γ-ray transitions in resonance-averaged neutron capture.

Because of the relatively large uncertainties quoted for the level energies from the (d,p) data, there has been some ambiguity in deciding if a given level (or which of a group of levels) is in fact populated in this reaction. Some of these instances are indicated in the cross-reference notations.
1999As05, in (HI,xnγ), report a rotational band based on the 16.5, 5/2+ state. Because of the tentatively established features of this band above the 358, 13/2+ state, the data on these higher-lying levels are not further given here. For this information, see the (HI,xnγ) Data Set.
