Condensed-phase effects on absolute cross sections for dissociative electron attachment to CFCs and HCFCs adsorbed on Kr
Bibliographic record
Abstract
We present measurements of absolute dissociative electron attachment (DEA) cross sections to CFCl3, CHF2Cl, and CH3CF2Cl adsorbed on the surface of Kr as a function of electron energy (0–10 eV). The DEA cross sections are measured to be ∼7.2×10−15 cm2 at ∼0 eV, ∼4.2×10−16 cm2 at 0.65 eV, and ∼7.8×10−16 cm2 at 0.89 eV for CFCl3, CHF2Cl, and CH3CF2Cl, respectively. This cross section is similar to the gas-phase value for CFCl3, while for the latter two molecules, it is orders of magnitude higher than the gaseous values. These results can be explained by considering the changes in the survival probability of the anion resonance and in the electron capture probability due to the decrease of the nuclear wave function overlap in the Franck–Condon region.

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.
