This paper presents the approach of a combined use of resonance integrals and average Maxwellian cross sections (MACS) at kT=30keV to test and validate the resolved resonance range or its reconstructed cross section curve. Based on these two integral measurements a sensitive and energy dependent test can be provided. These two integral quantities cover with their neutron spectra the energy region between E n =0.5eV up to several hundred keV, respectively, with different weighting. Our principal motivation is to produce a validation tool, sensitive to the lower and upper parts of the resonance region through the difference in the applied 1/E and kT=30keV Maxwell–Boltzmann spectra of the resonance integral and MACS data.
