Zusammenfassung	The activity concentrations of ⁶³ Ni solution was determined ny means of two liquid scintillation counting techniques: the TDCR method and the CIEMAT/NIST efficiency tracing techniques. The results of both methods are in excellent agreement, provided that the ⁶³Ni beta spectrum calculation accounts for the atomic exchange effect. Thus, new beta spectrum calculations resolve a discrepancy that has been found in previous analyses. The influence of the computed beta spectrum on the final uncertainty of the activity concentration is discussed.
