“…The 𝐶 s parameter represents the count rate at saturation, 𝑘 0 Au is the k0 value, 𝑘 𝜀 is the efficiency ratio between analyte and monitor, 𝑘 𝛽 is the correction due to neutron flux gradient for measurement and standard samples, 𝐺 th and 𝐺 e are neutron self-shielding corrections, 𝑓 is the thermal to epithermal conventional flux ratio, 𝑄 0 is the resonance integral 1 𝐸 ⁄ to 2200 m s -1 cross section ratio, 𝐸 ̅ r is the effective resonance energy, 𝛼 is the deviation from the 1 𝐸 ⁄ trend of the epithermal flux, 𝑚 is the mass, 𝜂 is the moisture correction and 𝑤 is the mass fraction. Details of the measurement model and its validation can be found in [4] and [5], respectively.…”
