Nonresonant inelastic x-ray scattering (NIXS) experiments have been performed to probe the $5d\text{\ensuremath{-}}5f$ electronic transitions at the uranium ${O}_{4,5}$ absorption edges in several systems characterized by either a localized or itinerant character of the $\text{U}\text{ }5f$ electrons, namely, ${\text{UO}}_{2}$, USe, US, and elemental uranium in the $\ensuremath{\alpha}$ form. For small values of the scattering vector $q$, the spectra are dominated by dipole-allowed transitions…

Studying low-energy corevalence transitions with bulk sensitivity using q-dependent NIXS
Absorption-based studies of low-energy atomic edges possess an inherent challenge in distinguishing surface and bulk contributions to the measured signal. The nature of the absorption process itself,
Unraveling 5f-6d hybridization in uranium compounds via spin-resolved L-edge spectroscopy
TLDR
This work probes the hybridization between 5f to 6d orbitals in uranium compounds using X-ray magnetic circular dichroism near U-L3 edge through the dipolar and quadrupolar spectral contributions, demonstrating the potentiality of this methodology to investigate a plethora of magnetic actinide compounds.
