The incoherent scattering function, S(x, Z)/Z, per electron for aluminium shown as a function of x = (sin θ)/λ. The Waller–Hartree theory (dotted line) is compared with the truncated impulse approximation in the tabulated Compton profiles (Biggs, Mendelsohn & Mann, 1975[link]) cut off at E < EB for each electron group (solid line). The third curve (dashed line) shows the simplification introduced by Ribberfors (1983[link]) and Ribberfors & Berggren (1982[link]). The predictions are indistinguishable to within experimental error except at low [(\sin\theta/\lambda)]. Reference to the measurements can be found in Ribberfors & Berggren (1982[link]).
