Although the correction appeared after so many years, it looks consistent with some possible abnormality signaled in the initial assignment. Indeed, in their {+150}Sm({+14}N,6n|g) study, 1981Dr07 observe the |g's in {+158}Er following |e decay with intensities which differ from those reported in the |e decay of the {+158}Tm ground state and, thereby, deduce the existence of an isomer. However they suggested in the text a half-life of about 20 s, while 20 ns was marked on their level scheme, with the former adopted (because the |g's were seen after the beam was turned off, so 20 s looked more reasonable), which however proved to be just a typografical error so 20 ns was finally adopted.

E$70.9 {I15} (HI dataset) if presumably measured 28.85|g to 42 level would be confirmed 
E$70 {I20} estimated by 2005Re18 from the absence of K x rays and of a ce transition with E(ce)<35 keV that suggests that E|g<50 keV for any transition in the IT decay. The isomer must lie above the 42 level since, if it were to lie below this level, the decay would have to take place to the g.s., and the implied B(E4)(W.u.) or B(M4)(W.u.) value would greatly exceed RUL. The most probable mode for the IT decay is to the 42 level. With the energy of the deexciting |g restricted to between |?8 keV (L x rays are observed) and |?50 keV, the energy of the isomer is estimated to lie somewhere between |?50 and |?90 keV. 1983Si20 conclude that the isomeric state is located within 100 keV above the g.s. 70.9 {I15} if the presumably measured 28.85|g to 42 level in the HI dataset would be confirmed. 
J log| {Ift}=6.4 (log| {If{+1u}t}=8.2) to 4+ and log| {Ift}=6.5 (log| {If{+1u}t}=8.2) to 6+. Since the side band populated in the heavy-ion reactions probably has K|p=5+, it is tempting to identify this state as the head of this band. If this is correct, then J|p would be 5+ for this state, with configuration=(|p 7/2[523] + |n 3/2[521]). Note that, from in-beam |g studies, 1990TeZX show a 161.8 level having J|p=5+ on their proposed level scheme which could be this bandhead, but no information is given to support either the energy or the J|p assignment of this level. Note also that, if the |e+|b{++} branching to the 3+, 987 level in {+160}Er is nonzero, a 5+ assignment to this level is ruled out.

J Based on the nearness of the energy separation of this level and the 8+ state at 2046 to the energy of the 3- octupole excitation built on the |n f{-7/2} state in {+153}Yb (1989Mc01), from in-beam studies of the |g's from {+102}Pd({+54}Fe,2pn), 1993Zh10 assign J|p=(11-) to this level. Presumably, it is the 3- octupole vibration built on the first 8+ state in {+154}Yb. Its observed decay mode (a single |g transition to the (10+) level) is consistent with an (11-) assignment.

E$Level reported in {+158}Ta |a decay (1997Da07). 
J$From a consideration of measured and calculated proton emission half-lives for the 10.5~ms state of {+166}Ir, 1997Da07 conclude that the proton emission is from the |p d{-3/2}, rather that from a |p s{-1/2} or |p h{-11/2} orbital. This, together with systematics which indicates that the odd neutron is in the |n f{-7/2} orbital, suggests that this {+166}Ir state has Configuration=((|p d{-3/2})(|n f{-7/2})). For this configuration, the Nordheim strong rule for angular-momentum coupling in odd-odd nuclides indicates that the J{+|p}=2- coupling lies lower in energy. Hence, the {+166}Ir ground state most likely has J{+|p}=2-. Since this level is fed by a succession of three unhindered (|DL=0) |a decays from the {+166}Ir ground state, its J{+|p} should be the same.

E$From 2021Ko07 
E$PREVIOUSLY: 59~{I9}, weighted average of 59~{I9} {+158}Ta |a decay (36.0 ms) (1997Da07) and 60~{I12} {+158}Ta |a decay (6.1 |ms) (2014Ca03) 
%EC+%B+$Value assumed by evaluator from the lack of reported |a decay and the fact that the measured half-life is comparable to that calculated for the |e decay, namely 1.18~s (2019Mo01). Also, |a systematics suggest %|a|?0.002. 
E$There has been some question as to whether this level is the same as the level that decays via |e to {+154}Yb. In their study of the {+154}Lu |e decay, 1988Vi02 assign the |e parent level as (7+). However, the evaluator has concluded, based on the information from the in-beam studies (1993Zh10,1996Zh09) of the {+154}Yb level scheme, that the J{+|p} value of the {+154}Lu parent in the |e decay is probably not (7+) but rather is (9+) (see the discussion in the {+154}Lu |e decay dataset). Throughout this evaluation, it has been assumed that the (9+) level reported here is the same as the parent state of the {+154}Lu |e decay. 
T$From weighted average of 0.96~s~{I10} (1981Ho10) and 1.16~s~{I5} (1988Vi02). Other: 1.1~s (1984HaZD). 
J$1988Vi02 report significant |e+|b{++} feeding from {+154}Lu to the (6+) and (8+) levels in {+154}Yb and from this conclude that J{+|p} for the {+154}Lu parent is (7+). They also indicate that this |e+|b{++} feeding pattern suggests a similar structure for these two final states. The odd proton and odd neutron in the {+154}Lu parent state are in the |p h{-11/2} and |n f{-7/2} orbitals, respectively. The implied low log| {Ift} values indicate strong Gamow-Teller transitions, which in this case would be |p h{-11/2}|)|n h{-9/2}. It is now believed, however, that the configurations of the two {+154}Yb final states are quite different (see the discussion in the {+106}Cd({+54}Fe,|a2p|g) data set, as well as those in the original studies (1993Zh10,1996Zh09)). Only one of these states, the (8+) level, can be fed by a strong Gamow-Teller transition. The transition to the (6+) level would be |p h{-11/2}|)|n f{-7/2}. It will be much weaker (and, possibly, may not take place). Thus, the basis for a (7+) assignment appears to be considerably weakened. The evaluator has chosen to adopt J{+|p}=(9+) for the {+154}Lu |e decay parent, in agreement with the systematics of the spins in this mass region.

J$The |a decay of this level has a small (|? 0.7) hindrance factor which suggests the initial and final states have the same spin and parity.

The 1+ case is ruled out by the beta strength function measured using the TAGS technique by 1995GaZW, which showed no feeding to the first 2+ level in {+158}Yb. 
T$Weighted average of 10.4 s {I10} from {+158}Lu |a decay (1979Al16,1979Be52) and 10.6 s {I3} from {+158}Lu |e decay (1983Ge08); others: 9 s {I2} (1983To01) and 8.9 s {I15} (1980Al14).

If a 3.09 transition to the 92.89 (4)- level existed, it presumably could not have been detected, but the other possible transitions (both |DK=(3)) should have been within the experimental range of 1969Tr02.
