Data are from ¹⁵³Gd(n,γ), ¹⁵⁴Eu β^- decay, ¹⁵⁴Tb ε decay (21.5 h, 9.4 h, and 22.7 h), ¹⁵⁰Nd(⁹Be,5nγ) and Sm(α,xnγ) reactions, Coulomb excitation, ¹⁵⁶Gd(p,t), ¹⁵²Gd(t,p), ¹⁵⁴Gd(e,e’), ¹⁵⁴Gd(d,d’), and ¹⁵⁴Gd(p,p’) reactions.

In a study of the β^- decay of ¹⁵⁴Eu, 2004Ku13 do not confirm the existence of the following levels, previously reported in thermal-neutron capture: 1276.99; 1294.19; 1295.09; 1698.51; 1702.04; 1838.61; and 1861.55. These levels and their associated γ’s are not included here. See the comments in the ¹⁵⁴Eu β^- decay and ¹⁵³Gd(n,γ) E=th data sets.

Levels: From the compilation of 1973Mu14 there are 48 n resonances below 1~keV in ¹⁵⁴Gd; the related measurements are given in 1974Ra23. See 1987Ma13 for data on 134 resonances from 0.48 to 2.76~keV. For a recent publication of n resonances for this, and other nuclides, see 2006MuZX.

Levels: For the labeling used to identify the cranked shell-model configurations, see the (⁹Be,5nγ) data set. For a discussion of the various band crossings in the cranked shell-model, see 1989Mo20 (⁹Be,5nγ).

Gammas: Unplaced γ’s are not included here; see ¹⁵⁴Tb ε decays (21.5 h, 9.4 h, and 22.7 h), ¹⁵⁴Eu β^- decay, and ¹⁵²Sm(α,2nγ).
