E(level)	E(gamma)	Comments
591.0	591	E(γ): Transition energy from measured E(ce)(K). No Eγ has been observed. M(γ): from K:L = 5:1 from ce data in ¹⁵⁶Gd(³⁶Ar,4nγ) (1999Le61).
723.6	723.5	M(γ): DCO=0.96 7 from ¹⁵⁶Gd(³⁶Ar,4nγ)
725	725	E(γ): Transition energy from the measured E(ce)(K). Note that the energy overlaps with the much stronger 723.9γ, E2 2⁺ to 0⁺ transition. M(γ): K:L = 5.4:1.0 from ce data in ¹⁵⁶Gd(³⁶Ar,4nγ) (1999Le61). The measured large α(K)exp=0.044 5 for the doublet 725γ indicate E0 component. α 767 keV 12 E0 transition was reported in ¹⁹²Po α decay (1998Al27), but the population of this state was questioned in the later ¹⁹²Po α decay work (2003Va16).
952.5	228.7	M(γ): A₂=-0.33 15, α(exp)=2.9 5 from ¹⁵⁶Gd(³⁶Ar,4nγ); E0 component inferred from large α(exp) and A₂ implies large E2 component. An M1 admixture should be expected, if K Ne 0 for the initial and final states.
