Using photoelectron spectroscopy to measure resonant inelastic X-ray scattering: a computational investigation

open access: yesJournal of Synchrotron Radiation, 2022
Resonant inelastic X-ray scattering (RIXS) has become an important scientific tool. Nonetheless, conventional high-resolution (few hundred meV or less) RIXS measurements, especially in the soft X-ray range, require low-throughput grating spectrometers ...
