The Bragg edge transmission (BET) analysis is a technique exploiting the presence, position and shape of the edges which form in time of flight transmitted neutron beams. This phenomenon is induced by the effect of coherent neutron scattering, so that strong components of neutrons, with precise wavelengths, are scattered by a crystalline sample at a specific Bragg angle (2). The transmitted beam presents a dip in correspondence with such a specific wavelength. When a polycrystalline material is analyzed, the combination of the dips appears as a large saw-teeth-like dip, with a sharp edge at the wavelength corresponding to the 2=180° scattering angle.By exploiting BET analysis, we plan to characterize, 9 steel reference standards, certified by Bureau of Analysed Samples Ltd, with amount of carbon ranging from 0.05 up to 1 weight %.
