Resonant Auger, resonant inelastic X-ray scattering and resonant X-ray emission spectroscopy at the SXRMB of the Canadian Light Source—recent commissioning results
Bibliographic record
Abstract
In this contribution, we present recent commissioning results from the SXRMB@CLS on the L3M4,5M4,5 Auger as a function of excitation energy from below to above the L3-edge of a Ru (0001) single crystal and a Nb metal foil, showing the resonant inelastic X-ray scattering (RIXS) like dispersion behavior as the excitation is approaching the threshold from below. The Auger lines exhibit a constant shift at excitation energy below the threshold with increasing excitation energy toward the threshold and become narrower at the threshold where RIXS and resonant X-ray emission (RXES) become a concerted process as resonant Auger (also known as Auger Raman because of the constant shift) becomes normal Auger. We also present RIXS and RXES results at the Nb L3-edge of Nb metal and the P and S K-edge of P2S5 and ZnS, respectively. These results show that SXRMB is ready for users to embark on systematic studies on both the electron and photon channel following core hole de-excitation at resonance and related phenomena.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
