Table 3 Activity of 47Sc at the time of separation (A(47Sc)), comparison of the calculated and measured 47Sc saturation yield (A(47Sc)calc and A(47Sc)meas) and of the optimal and measured relative 47Sc activity (a(47Sc)opt and a(47Sc)meas) after irradiation with thermal neutrons at ILL (irradiations ILL 1–5) and BR2 (irradiation SCK.CEN)
