N1 - Funding Information:
The authors thank Dr Norman Booth and Dr Nozomu Adachi for help with the experiment and Mr Toshinori Ishida, Dr Hirotaka Sato, Professor Masato Ohnuma and Professor Michihiro Furusaka for stimulating discussions. The neutron scattering experiments were preformed at the BL15 TAIKAN of J-PARC with the approval of CROSS (Proposal Nos. 2012B0152 and 2014A0301) and QUOKKA at the Australian Centre for Neutron Scattering, Australian Nuclear Science and Technology Organisation (ANSTO). Travel expenses for the SANS experiments performed using QUOKKA were supported by General User Program for Neutron Scattering Experiments, Institute for Solid State Physics, The University of Tokyo (proposal No. 14900), at JRR-3, Japan Atomic Energy Agency, Tokai, Japan. Funding for this research was provided by: 22nd ISIJ Research Promotion Grant and KAKENHI (award No. 26870313).

N2 - Recent progress of pulsed neutron sources has enabled energy-resolved analysis of neutron attenuation spectra, which include information on neutron scattering. In this study, a new analysis technique for small-angle neutron scattering (SANS) is demonstrated. A clear difference is observed in the neutron attenuation spectra between steels with different nanostructures; this difference can be understood as arising from attenuation due to SANS. The neutron attenuation spectra calculated from the corresponding SANS profiles agree well with the experimentally observed attenuation spectra. This result indicates that measurement of neutron attenuation spectra may enable the development of a novel experimental technique, i.e. energy-resolved SANS.
