163Gd produced as a fission fragment (1982Ge07) from 252Cf SF decay, followed by chemical separation. It was identified by observation (1982Ge07) of ten γ rays with a common T1/2 in the Gd fraction and growth and decay of the 163Tb daughter.
2006SaZS report five γ rays in 163Gd from the decay of 163Eu, but do not place them in the level scheme. This information is not further mentioned here. See the 163Eu β- Decay data set for it.
Q-value: Note: Current evaluation has used the following Q record $ 3170 70 5270 syst 10130 syst -1700 syst 2009AuZZ,2007Ha57
Q-value: S(n),S(p),Q(α): from 2009AuZZ and 2003Au03. The uncertainties, also from systematics, for these quantities are: for S(n), 300; for S(p), 420; and, for Q(α), 310 (2009AuZZ,2003Au03).
