Title: Reply to: Reconsidering X-ray plasmons

Abstract

In this response we show a spectral and X-ray intensity analysis that unequivocally proves a spectrally resolved plasmon reported in ref. 1. The analysis takes the f-sum rules into account, is consistent with the independently and simultaneously measured wavenumber-resolved X-ray scattering signal and compares well with advanced elastic feature modelling, including density functional theory for molecular dynamics (DFTMD) as well as pseudoatom molecular dynamics.

Fig. 1 Fig. 1: Comparison of signals. a, Backscatter signal plotted with the forward spectrum and the theoretical fit to the data. The right y axis (blue) shows the X-ray photons measured for a single shot in the backscatter data. The left y axis shows the X-ray photons measured for a singlemore » shot in the forward scatter data, and the expected signal of the backscatter data as observed on the forward spectrometer based on the 2.45x decrease in the integrated elastically scattered signal WR.(k). b, A single-shot forward spectrum together with the best-fit source function signal (green shading), the integrated plasmon signal (SpL(k), blue shading) and the theoretical fit to the forward spectrum. The fit is calculated for $p$=2.32$p$0, and Te=1.75eV. c, A multishot-averaged forward scattering spectrum, the best-fit source function signal (green shading), the plasmon signal (blue shading) and the theoretical fit to the forward spectrum, where the best fit is achieved at conditions of $p$=$p$0, (X-ray only). The spectra in a-c clearly show downshifted plasmon signals in the forward spectrometer with no plasmon in the backscatter spectrometer as expected; a similar X-ray scattering spectrum, for an identical experimental configuration, has been previously reported.« less
