X‐Ray Study of a MgLi Alloy With a Reflection Zone Plate Spectrometer on an Electron Microprobe
Bibliographic record
Abstract
ABSTRACT A MgLi dilute alloy (6% wt. Li) has been studied by x‐ray emission spectroscopy in the ultra‐soft x‐ray range, 40–60 eV. For this purpose, a high‐resolution reflection zone plate spectrometer, working as a variable line grating spectrometer, was used on an electron probe microanalyser. With the experimental conditions, current and acceleration voltage of the incident electron beam, geometry, CCD detection, the Mg L emission band is easily observed. The Fermi edge of this band shifts toward the low photon energies with the Li content. The Li K emission band is hardly detectable despite the non‐negligible lithium mass fraction in the alloy. This is explained by the reabsorption of the lithium emission by the magnesium atoms, the reabsorption effect being strong in the present geometrical conditions of the experiment.

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.
