Abstract
Vacuum-ultraviolet emissions following the dissociative excitation of ${\text{H}}_{2}\text{S}$ by electron impact at 100 eV incident energy have been measured. The absolute photoemission cross sections are presented over the wavelength range from 94 to 170 nm and the H, SI, or SII transitions producing the features identified. The measured cross section of the Lyman-$\ensuremath{\alpha}$ emission at 121.6 nm for an electron-impact energy of 100 eV is $(9.79\ifmmode\pm\else\textpm\fi{}0.67)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}18}\text{ }{\text{cm}}^{2}$. Excitation functions of the dominant H and SI emission lines are shown for electron-impact energies from threshold to 300 eV. We study the near-threshold region of the excitation functions and use the measured threshold energies to identify the dominant fragmentation channels.

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; both teacher heads agree on what is shown here.
