First-principle calculation of resonant X-ray emission spectra

An interesting theoretical paper on the calculation of K edge resonant X-ray emission spectroscopy has been published recently. The crystalline band structure was calculated using a quasiparticle self-consistent GW implementation, and then coherent spectra were obtained in the Kramers-Heisenberg formalism. The calculated results for ZnO were compared with experiments. For more information, see the paper, "First-principles calculation of resonant x-ray emission spectra applied to ZnO", A. R. H. Preston et al., Phys. Rev. B83, 205106 (2011).
