Neutron data for Cr, Fe and Ni from the ENDF/B-IV, SOCRATOR and BNAB-78 libraries are compared each other and with the results of the experiments sensitive to the capture, inelastic scattering cross-sections and its resonance structure for the investigated materials. Experiments on the Van-de-Graaf accelerators, reactor beams and critical assemblies was used.

KEYWORDS: experiments, constructional materials, BNAB-78, ENDF/B-IV, SOCRATOR system, group constants, results of calculations
