E(level): From a least-squares fit to γ-ray energies, assuming ΔEγ=1 keV if not given
Jπ(level): J|>6 are as proposed by 1998Ce03 based on ΔJ=1, dipole transitions and shell-model predictions
M(γ): From DCO ratios in (58Ni,pn2αγ) for high-spin states (J>6) and from ce data in 98Cd ε decay for the rest, unless otherwise noted.

107.28 | 107.28 | E(γ): The ordering of 107γ and 61γ is from 2017Pa35 in 9Be(124Xe,Xγ), based on the non-observation of 161-ns delayed component for the 61γ in their spectra. 1992Pl01 had proposed a reversed ordering, defining the intermediate level at 60.55 keV, instead of the present 107 keV |
167.83 | 60.55 | E(γ): The ordering of 107γ and 61γ is from 2017Pa35 in 9Be(124Xe,Xγ), based on the non-observation of 161-ns delayed component for the 61γ in their spectra. 1992Pl01 had proposed a reversed ordering, defining the intermediate level at 60.55 keV, instead of the present 107 keV |
514.99 | 347.18 | M(γ): proposed by 1992Pl01 in 98Cd ε decay but no experimental evidence is given. |

Other measurements:
1978Hu11: 98Ag identified and produced. Later studies: 1982Ku15, 2000Hu17
2014Fe01: E(36Ar)=125 MeV beam from Leuven cyclotron facility. Target was >98% enriched 64Zn and natural Zn; but stated reaction implies 66Zn target. Measured hyperfine structure using in-gas-cell laser ionization spectroscopy. Deduced magnetic dipole moment, mean-square charge radius and isotope shifts. Measurements made using LISOL facility at cyclotron center in Leuven.
