From: X-ray Thomson scattering absolute intensity from the f-sum rule in the imaginary-time domain
(a) XRTS intensity (solid green) and SIF (dashed blue) of carbon measured by Voigt et al.35 at the European XFEL. The scattering angle and wave number are given by \(\theta =155^\circ\) and \(q=5.94\,\)Å\(^{-1}\). (b) Corresponding convergence of the normalized static structure factor \(S_{ee}(\textbf{q})=F_{ee}(\textbf{q},0)\) with the integration range x. The solid black curve shows an exponential fit to the deconvolved data [cf. Eq. (8)], and the red data point marks our final estimation of \(S_{ee}(\textbf{q})=0.783\pm 0.003\).
