156GD4D 5 multiploarities and 5 MR.
156GD cE TI$Since |DJ=3, the g.s. |e branch has been assumed to be negligible.
156GD2cE Values for the excited levels are from |g-intensity balances and their
156GD3cE accuracy is limited by the incompleteness of the decay scheme. There
156GD4cE are several unplaced |g's with I|g of 0.03 to 0.3%. So, computed
156GD5cE I|e+I|b{++} values<0.10% are not included, and such values smaller
156GD6cE than|?0.3% should be regarded with caution.
156GD cG There are several |g's reported by 1961Ha23 from ce data that
156GD2cG have not been verified in later measurements and, therefore, are not
156GD3cG included in the table. These are at
156GD4cG 170.8, 943.4, 2090, 2105, 2140, 2268, 2281, and 2310 keV.
156GD cG |g's reported by 1970Fu06 as "questionable assignment" and
156GD2cG not reported by 1971Mc13 or 1980Iw04 are not included in the table.
156GD3cG These are at 499.69, 956.28, 725.78, and 1073.69 keV.
156GD cG In comparing with these data, above 1870 keV the E|g of
156GD2cG 1967Ke15 must be increased by 1 to 3 keV.
156GD cG E From 1970Fu06 unless otherwise noted. The only other
156GD2cG extensive list of E|g is given in 1971Mc13. The unplaced |g's are
156GD3cG from 1970Fu06, 1971Mc13, and 1980Iw04.
156GD cG RI From 1980Iw04 for |g's above 290 keV and 1971Mc13 below this
156GD2cG energy. These are the only extensive lists of I|g.
156GD cG M,MR$From {+156}Gd Adopted |g radiations and based on studies of this
156GD2cG decay (1959Of11, 1961Ha23, 1962Lo01, 1967Ke15, 1968We17, 1970Fu06,
156GD3cG 1970Pe10, 1971Mc01, 1972Ha29, 1975Ul01, 1976Ya11, 1979Ri17, 1981Mc06,
156GD4cG 1983Li06), as well as studies of {+156}Eu |b{+-} decay, Coul. ex., and
156GD5cG (HI,xn|g) and (n,|g) reactions.
156GD cG E(U) From 1980Iw04.
156GD cG E(T)$From 1971Mc13.
156GD cG E(W),RI(W)$From 1971Mc13 and reported as probable doublet.
156GD cG E(Y)$Previously unplaced. Placement is that proposed by 1995GrZW, using
156GD2cG data from the {+155}Gd(n,|g) reaction.
156GD cG RI(V) From 1971Mc13.
156GD cG RI(X)$Establishing the |g-decay patterns of the two 1934 levels
156GD2cG (J{+|p}=2- and 3-) is problematic, in that a number of |g's are
156GD3cG proposed to deexcite both of them. These levels are also populated in
156GD4cG the (n,|g) reaction. In this evaluation, the evaluator has used the
156GD5cG data from both the (n,|g) reaction and the {+156}Tb |e decay to deduce
156GD6cG the split in intensity of these |g's between these two levels. For the
156GD7cG details of this analysis, see the discussion of this point in the
156GD8cG {+156}Gd(n,|g) E=th Data Set.
156GD cL The coincidence data on the drawings are from 1967Ke15 and
156GD2cL 1971Mc13.
156GD cL E From least-squares fit to |g energies.
156GD cL J From {+156}Gd Adopted Levels.
156GD cL T From {+156}Tb decay experiments only; all values are given in
156GD2cL the {+156}Gd Adopted Levels.
156GD cL E(Z)$Using data from the {+155}Gd(n,|g) reactions, 1995GrZW propose the
156GD2cL placement of several previously unplaced |g's, which involves the
156GD3cL introduction into the decay scheme of several levels, known from other
156GD4cL studies but not earlier reported to be populated in the {+156}Tb |e
156GD5cL decay. Where decay modes are reported for these levels, they are
156GD6cL included here.
156GD cL $1995GrZZ, from resonance-averaged (n,|g) data, report the population,
156GD2cL in the {+156}Tb |e decay, of the following levels and J{+|p} values:
156GD3cL 1970.43, 3-; 1995.12, 4-; 2010.35, 4+; 2024.94, 3-; 2139.84, 3+;
156GD4cL 2227.62, 3-; and 2265.75, 3+. No decay modes are given for these
156GD5cL levels. The evaluator has chosen not to include them here.

156GD cG $1995GrZW place this |g from a 1995 level, possibly from considerations
156GD2cG of the (n,|g) data. However, I|g(697.7|g) in the (n,|g) |g spectrum is
156GD3cG already smaller than expected, based on comparison of the I|g values in
156GD4cG this and the |e-decay spectra. The evaluator has chosen to show this |g
156GD5cG as still unplaced and the 1995 level as not observably populated in the
156GD6cG |e decay.
