Table 4.
SACS in a 252Cf(sf) neutron field, ⟨σ⟩, are tabulated for various dosimetry reactions. SACS were either calculated with Mannhart’s PFNS or this evaluation (AIACHNE). Also, experimental data are shown as retrieved from Table 18 in [48] and selected high-energy SACS measured in Řež retrieved from Table 19 in [48] (with bold reaction ID). The variable δ denotes the relative uncertainty of SACS. Both, cross section and PFNS uncertainties are considered using Equation (7).
