Figure 1
(a) Neutron cross sections per atom for the SDSS sample. The cross-section components defined in equations (1)

and (2)

are shown. Primary hkl reflections for both the ferrite and austenite phases are labelled, with austenite indices indicated in italics. (b) The total neutron cross section for amorphous PE (chemical formula CH₂). Also plotted are the total cross sections for H bound in CH₂, free hydrogen, and interstitial H in f.c.c. Fe–Cr–Mn–Ni steel using PDOS from Danilkin et al. (2003

). See text for further discussion.
