General Comments:

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.

Theory references: consult the NSR database (www.nndc.bnl.gov/nsr/) for 10 primary references, 9 dealing with nuclear structure calculations, and one with decay modes and half-life.

Q-value: Q(εp)=2240 50, S(2n)=24700 100, S(2p)=7960 30 (2017Wa10)

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   107.28E(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    60.55E(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
