Abstract
We report on a modeling study of the polarization properties of the Ly-α line in sulphur. The lower energy (J = 1/2) fine-structure component is unpolarized, while the polarization degree of the higher energy component (J = 3/2) can serve as a signature of an anisotropic electron distribution. We calculate the polarization degree of the J = 3/2 component with the help of a magnetic-sublevel population atomic kinetics model for plasma conditions that can arise in laser-produced plasma experiments. This demonstrates how observed polarization properties of the Ly-α could be connected with the characteristics of an anisotropic electron distribution.

How this classification was reachedexpand
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.
