Resonant InelasticX‐ray Scattering

Abstract Two resonant inelastic x‐ray scattering techniques are discussed: nuclear resonance inelastic x‐ray scattering (NRIXS) and resonant inelastic x‐ray scattering (RIXS). In NRIXS, the x‐ray energy is tuned around the nuclear excited level of the targeted Mössbauer nucleus to quantitatively probe the vibrational dynamics of the respective isotope, regardless of the atoms surrounding it. In RIXS, the incident energy coincides with an electronic absorption edge, probing intrinsic excitations in metals and other materials. We present the characteristics of these two techniques with their experimental requirements and include a few examples from the literature.
