(note that 1992Ha10 quote the value from 1982Sc15 (both papers have many of the same authors) as %|a=0.0087 {I7}.) However, in none of these studies were the absolute I|g values measured. 1995Hi12 estimate the absolute I|g values by requiring the sum of the intensities of the |g's feeding the g.s. to be 100% (K. S. Toth, priv. comm. (Oct., 1996)). 1992Ha10 assume the I|g value of the strongest |g transition in the spectrum to be 100%. In their paper, 1982Sc15 report I|a/I|g(174|g)=0.00091 {I9} but, in their data tables, they show the value given here for them. Note, also, that all three of these approaches lead to situations in which the I|g values used may be larger than the actual ones. Consequently, the inferred %|a values should perhaps be regarded as upper limits for the correct value. Nonetheless, the listed value agrees well with the result expected on the basis of systematics.

MOMM1$from collinear laser beam spectroscopy (2000Ye02) 
%IT,%EC+%B+$the microchannel plates (1997Ca39) are sensitive to |g rays, low-energy electrons and x rays, so it is unclear whether this isomer decays by IT or |e decay or both. However, the analogous isomer in {+169}Yb exhibits %IT=100. Also, significant |e decay from this 1/2[521] level to the 79 s, 1/2[541] isomer at 71.1 keV in {+171}Lu should have been evident in the measured activity decay curve, but was not. Consequently, it seems likely that %IT=100 for this level.

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

 -ea- I|g for |g rays deexciting this level do not agree with those from the 2+ and 4+ levels at 1513 keV observed in (n,|g) E=thermal. See also {+178}Lu |b{+-} decay (28.4 min) for population to a 1513.6 level. -ea- From an E0 component in the 1420|g to the 2+ 93 keV level, and the E2 1513|g to 0+ g.s. (1972Li03), a J|p=2+ assignment would be firmly established. On the other hand, the E0 component in the 151 keV transition (1972Li03), which connects to the 2- 1362 keV level, implies a J|p=2-. Furthermore, comparing the I|g branching ratios for the four |g placed as deexciting this state, both here and in the {+178}Ta EC (9.3 M) dataset, shows very good agreement for the 1420 and 1513 keV transitions, but disagree significantly for the two low energy |g rays. These results provide rather strong indication that this level is, at least, a doublet. One of the components could possibly be the 2+ state also seen in several of the neutron capture experiments, deexciting via the 1420 and 1513 keV transitions. The other might probably be a J|p=2- state connected to the 2- 1362 keV level by the 151 keV |g. Nothing certain could be deduced about the placement of the 203.8|g since no data are available to define its multipolarity.

%P The calculated (1997Mo25) half-life for |b emission is |?0.33 s, which suggests that this branch does not compete to any significant extent with proton emission. 
E in addition to h{-11/2}, the |p s{-1/2} and |p d{-3/2} orbitals are also expected at low energies in {+155}Ta, but these latter two should have a much shorter T{-1/2} value and be produced with a smaller cross section and hence may have escaped detection. Thus the |p h{-11/2} orbital, which is the one from which proton emission takes place, may not Be the g.s.. However, the agreement of the deduced S(p) value with systematics suggests that it is close to the g.s. (i.e., x is likely to be small). 
J measured T{-1/2} value is consistent with l=5 proton emission. It is much larger that that expected for l=0 and l=2 emission, the other two possibilities based on the available proton orbitals. Since the g.s. of the daughter nuclide, {+154}Hf, has J|p=0+, this establishes |p h{-11/2} as the configuration of the initial state.

J |g branching to 47/2+ and 45/2+ levels argues against J=47/2; J|p=49/2- very unlikely because 989|g would then have to be a |DK=6, M2 transition, inconsistent with measured T{-1/2}. 
T from fit to background-subtracted time spectra from ({+7}Li,4n|g) produced by gating on cascade transitions in K|p=37/2+ band (2004Ko58). Unexpectedly short T{-1/2} attributed to mixing with nearby J=49/2 member of K|p=37/2+ band via a very small interaction matrix element.

J$Based on the large total intensity for the 142.9|g, depopulating the 2+ state of {+188}W, which is fed in |b-decay of {+188}Ta and the proposed configuration. The assignment is tentative. The ground state for even-N Ta (Z=73) nuclei are assigned 7/2+, resulting from the |p7/2[404] orbital. Considering the observed neutron states in {+187}W (N=113), a neighbouring nucleus that is expected to have similar deformation as {+188}Ta, (0.0 keV, 3/2[512]; 145.7 keV, 1/2-[510]; 330 keV, 7/2[503]; 350 keV, 9/2[505] and 410 keV, 11/2[615]), one may expect that the |n7/2[503] orbital is closest to the Fermi surface in {+188}Ta (N=115), and hence, the |p7/2[404]~#|n7/2[503] configuration. The Gallagher-Moskowski rule favours the K|p=0- over 7- assignment. The J|p=1- state within this configuration may be lower than the expected K|p=0- bandhead, depending on the size and sign of the Newby shift, which are unknown at present. The |p7/2[404]~#|n9/2[505] configuration should be considered as an alternative, but in such a case the Gallagher-Moskowski rule would favor K|p=8- over 1- assignment.

E order of the 290-182 |g-ray cascade is consistent with coincidence transition intensity balance, but not with singles transition intensity balance.

Compiler obtains weighted average of 23.802 h {I34}, which could have been adopted as 23.80 h {I4}. Uncertainty includes statistical, fitting and systematic. 2019Kr02 point out that their value is in better agreement with 23.72 h {I6} from 1964An02 (J. Inorg. Nucl.

%A$From 2007Pa27. The calculated T{-1/2} for |b decay is |?0.24~s (1997Mo25), which suggests that |b decay does not contribute significantly to the decay of this state. 2007JoZX report %p=92. 
E$From the systematics of the separation of the 1/2+ and 11/2- states in the heavier odd-mass Re isotopes, the excitation energy of this level is suggested to be|?160 {I50} (G. Audi, private communication to the evaluator, (March, 2010)). 2006Jo10 suggest that this level energy May be|?120. 
J$From l=5 proton transition to the {+158}W g.s. (J{+|p}=0+) (2006Jo10). l=5 is deduced from comparison of the measured T{-1/2} value, with those expected for l=0, 2 and 5 emission, the three possibilities based on the available proton orbitals. Since the g.s. of the daughter nuclide, {+158}W, has J{+|p}=0+, this establishes |ph{-11/2} as the configuration of the initial state.

%EC+%B+$from gross |b-strength function calculations of 1973Ta30 as quoted by 1979Ho10. 
J$very tentative 2- for g.s. and 9+ for isomeric state based on the following considerations: for Z=75, valence proton orbitals are h{-11/2}, d{-3/2}, and s{-1/2}; and for N=89, valence neutron orbitals are h{-9/2}, f{-7/2}, and i{-13/2}. In neighboring {+166}Ir odd-odd nucleus, following configurations and J|p were proposed by 1997Da07: [|pd{-3/2}~#|nf{-7/2}]{-2-} for |a-decaying g.s. and [|ph{-11/2}~#|nf{-7/2}]{-9+} for |a-decaying isomeric state. The J|p assignments for these configurations were based on the Nordheim rules. Similar assignments were suggested for the |a-decaying g.s. and isomeric state in {+170}Au by 2004Ke06 and for {+172}Au by 2009Ha42. It is possible that the |a-decay chain {+172}Au |) {+168}Ir |) {+164}Re |) {+160}Ta |) {+156}Lu |) {+152}Tm follows a trend of |a decays of 2- g.s. and 9+ isomeric state, as the J|p=2- for the ground states and 9+ for the isomers in {+156}Lu and {+152}Tm seem fairly secure. 2017Au03 (in NUBASE-2016) assign (2-) for g.s. and (9+) for the isomeric state, probably from favored |a-decay chain starting with {+172}Au and ending in {+152}Tm, as shown above.
