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.

Resonant inelastic x-ray spectroscopy on UO2 as a test case for actinide materials

“…After fabrication of the sample in the sputtering chamber at the University of Bristol [27] it was transferred in a 'vacuum suitcase' to the Diamond Light Source. By using an interlock system, the sample was transferred into the vacuum chamber of beamline I21 [28] without any contact with air. At an incident x-ray energy of 778 eV (λ ≈ 16 Å) the 1/e attenuation length into UO 2 at an angle of incidence of ∼ 20 • is given by Henke et al [29] as 40 nm.…”
