General Comments:

Other measurements:

1997Gr02: identification of an isomer in 98Cd from separation of fragments from Ni(112Sn,X) at E=63 MeV/nucleon. α total of eight counts were assigned to a possible (8+), 0.2-μs isomer. Deduced T1/2 of the isomer. See also 1998GrZS for T1/2 of the isomer populated by fragmentation of 106Cd (ENAM conference Proc. p430, 1998, Bellaire, Michigan)

1978El09, 1992Pl01: 98Cd produced by spallation reaction Sn(p,x) at E=600 MeV followed by mass-separation

1969HaZU: 92Mo(12C,6nγ),E=70-95 MeV. α 1435γ assigned tentatively to deexcite first 2+ level in 98Cd

Q-value: Measured Q(β-)=-12930 400 (2019Pa16, from β- spectrum). 2017Wa10 give -13740 300 from systematic trend.

Q-value: Estimated uncertainty for S(n)=300 (2017Wa10)

Q-value: Q(εp)=2880 50, S(2n)=28210 400 (syst), S(2p)=6030 50 (2017Wa10)
