Comparison of efficiency-traced massic activities $C_{{\mathrm{A},}^{63}\text{Ni}}$ of solutions M3, M4, and M5 (see Fig. 1)

Solution Identifier (cocktail series)	$C_{{\mathrm{A},}^{63}\text{Ni}}/\text{kBq}\cdot {\mathrm{g}}^{-1}$
M3 (K,L)	50.23 ± 0.11
M4 (M)	50.24 ± 0.15
M5 (N)	50.24 ± 0.31

^aAll massic activities are normalized by the appropriate gravimetric dilution factors to solution M3, which represents the present calibration. See Table 1 for compositions of LS cocktails of the appropriate cocktail series for each solution. The uncertainties are the standard uncertainties corresponding to the variability in the massic activity due to reproducibility between LS cocktails in a given cocktail series.
