J(307.2) is restricted to 5/2, 7/2, 9/2 by |g's to 5/2+ and 7/2-. J(307.6) is limited to 5/2, 7/2 by M1 |g to 5/2+ and M1,E2 |g to 7/2+.

T$from decay curve for |g rays (1999Xi04), probably the 121.6|g. Full details of this measurement are not available. 1999Xi04 propose this isomer to be a low-spin without giving any J|p assignment. With (9/2-) for the g.s., this isomer could only have 1/2 or 3/2 to explain the long half-life. 2012Au07 propose 1/2+ from systematics. In view of overlapping half-lives of the two activities and in the absence of detailed data for decay, the evaluators consider the existence of this isomer as uncertain

In this LRSW analysis the uncertainty of the 1992Un01 value is increased from 0.07 to 0.185 so its relative weight is reduced from 88% to 50%. The two most precise values, 241.6 {I2} and 239.47 {I7} are very inconsistent, and the reduced-|h{+2} for the average of the six values is 30.0 with the original uncertainties and 21.8 after the one uncertainty is increased. The Adopted value from the final weighted average is 240.44 with uncertainties of 0.13 internal and 0.61 external; the adopted uncertainty is 1.0, so that it includes the most precise value, namely, 239.47. Other measurements are 239.63 d {I4} (1982HoZJ, replaced by 1992Un01), 240.9 d {I6} (1970LyZZ, assumed to be same data as 1972Em01), and those without uncertainties 200 d (1958An34) and 225 d (1949Ke01). 
T The omission of the very low value of 1989Po21 would not make a significant change. With the modified uncertainty for 1992Un01, the weighted average would be 240.49 with a reduced-|h{+2} of 16.6.

However, there seems to be no evidence from recent in-beam gamma-ray experiments, that a 5/2+ state is populated.

%B- |g radiations following the |b{+-} decay to {+156}Dy have not been reported, so the |b{+-} branching is taken to be zero in the determination of the %|e+%|b{++} value. Only decay to the 2+ and 4+ members of the ground-state band would be allowed by the Q(|b{+-}) value. The lack of observed |e decay to the 2+ and 4+ members of ground-state band in {+156}Gd lends support to this conclusion. 
%B- The first-forbidden B- decay to the 2+ level of 156DY at 138 keV should have LOGFT GE 5.9 (1973Ra10). This only limits the B- branching to LE 50%. So, any real limit wiil have to come from a limit on the 138-keV G intensity.

The 1/2[411] band, which is mixed with |g-vibrational components, has its bandhead at 597 keV.

The M1 |g's from members of this band to the ground-state band support the 1/2[411] component; and the fact that the decoupling parameter is 0.05 times the value expected for this orbital supports the presence of the vibrational components.

Because of the large reduced-|h{+2} value implied using the listed uncertainties, the following choices were adopted in computing this average: the quoted uncertainty in the 1971Ba28 value (0.02 d) was increased to 0.04 d; the value, 7.20 d {I7}, of 1958Ba44 was not included; and the quoted uncertainty (0.0005 d) in the value from 1989Ab22 was increased to 0.05 d. (Note that even doubling the uncertainties in the last two T{-1/2} values included in the average does not materially alter the adopted value.)
