Resonantly excited cascade x-ray emission from La
Bibliographic record
Abstract
We are monitoring the intensity of the La $5p\text{\ensuremath{-}}4d$ emission for La metal while scanning across the deeper lying $3d\text{\ensuremath{-}}4f$ photoexcitation resonances of the same atom. A strong resonant enhancement in the integral intensity of the La $5p\text{\ensuremath{-}}4d$ fluorescence emission is observed, which is due to cascading decay of the resonantly excited $3{d}^{9}4{f}^{+1}$ configuration. The corresponding emission spectrum features a complex satellite structure reflecting the multitude of transitions taking place in a variety of multi-vacancy configurations created by the cascade. We calculate the probability of $5p\ensuremath{\rightarrow}4d$ emission produced by the cascading decay and then take into account self-absorption of the emitted photons. This model provides good agreement with the experimental results. The number of $4d$ vacancies increases immensely due to electronic cascades. We also observe an enhanced integral intensity in the $5p\text{\ensuremath{-}}4d$ fluorescence compared to our calculations, which we attribute to intra-atomic resonance processes.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
