Abstract
We present measurements on the trapping of 0--3 eV electrons in ${\mathrm{H}}_{2}\mathrm{O}$ ice films covered with a submonolayer of ${\mathrm{N}}_{2}$ molecules. At the energy of the ${\mathrm{N}}_{2}^{\ensuremath{-}}{(}^{2}{\ensuremath{\Pi}}_{g})$ shape resonance, the absolute cross section for electron trapping in ice is $\ensuremath{\sim}5.5\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}16}{\mathrm{cm}}^{2}$, similar to that for vibrational excitations of gaseous ${\mathrm{N}}_{2}$ via the resonance. This result, indicating that nearly all electrons from autoionization of ${\mathrm{N}}_{2}^{\ensuremath{-}}{(}^{2}{\ensuremath{\Pi}}_{g})$ are transferred to electron traps in ice, is explained by superinelastic electron transfer from ${\mathrm{N}}_{2}^{\ensuremath{-}}{(}^{2}{\ensuremath{\Pi}}_{g})$ into preexisting traps in polar ice, leaving ${\mathrm{N}}_{2}$ in high vibrational excited states.

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.
