Abstract
Observations of the $(3{d}^{10}4{s}^{2}){}^{1}{S}_{0}\ensuremath{\rightarrow}(3{d}^{10}4s5s){}^{3}{S}_{1}$ excitation process in zinc, with incident spin-polarized electrons, show significant deviations from expectations for a pure electron exchange transition. This result, derived from values of up to 10% of the Stokes parameter ${P}_{2}$ (aligned linear polarization) of the light emitted in the $(3{d}^{10}4s5s){}^{3}{S}_{1}\ensuremath{\rightarrow}(3{d}^{10}4s4p){}^{3}{P}_{0,1,2}$ optical decays, is very different from predictions of near-zero values from general theory as well as sophisticated, relativistic close-coupling and distorted-wave numerical models. Although the linear light polarization ${P}_{2}$ may be nonzero by parity conservation, it was expected to vanish due to dynamical symmetries.

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; both teacher heads agree on what is shown here.
