Here 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 account2,3, 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)1 as well as pseudoatom molecular dynamics4.
