178HF DL I|g of |g rays deexciting this level do not agree with those
178HFxDL from the 2+ and 4+ levels at 1513 keV observed in (n,|g) E=thermal.
178HFxDL See also {+178}Ta |e decay (9.31 min) for population to a 1513.64
178HFxDL level.
178HF DL
178HFxDL =======================================================================
178HFxDL -ea- This level, seen both in the {+178}Lu B- (28.4 m) and
178HFxDL {+178}Ta EC (9.31 m) decays, is actually a multiplet of several
178HFxDL components, (see adopted levels). This can be seen from the fact
178HFxDL that two of the transitions listed here (151 and 203 keV) are not
178HFxDL reported as deexciting this level in any of the other datasets, even
178HFxDL though by the intensity reported here they should have been seen.This
178HFxDL possibly suggests a different structure for the deexciting state.
178HFxDL From the reaction {+177}Hf(n,|g) with thermal neutrons (see indicated
178HFxDL dataset), the other two (1420 and 1513 keV) are shown as actually
178HFxDL deexciting two different states: the 4+ 1513.8 keV, and the 2+ 1513.6
178HFxDL keV levels, respectively. It is also possible that these transitions
178HFxDL may be close lying doublets placed twice in the level scheme.

178HFxDG -ea- 1975Ka15 report Eg=203.8(2) keV, Ig=5.1(14), deexciting the
178HFxDG 1513 keV level, and Eg=204.1(2), Ig=1.1(3), from the 1566 keV level.
178HFxDG 1973Or03 report a single gamma Eg=203.8(5), Ig=3.9(9). It is not clear
178HFxDG if the 1973Or03 data contain contributions from both transitions.
