Coulombic and pre-Coulombic geometry evolution of carbonyl sulfide in an intense femtosecond laser pulse, determined by momentum imaging
Bibliographic record
Abstract
The Coulomb explosion of OCS in laser pulses of 55 fs and peak intensity of $2\ifmmode\times\else\texttimes\fi{}{10}^{15} {\mathrm{W}\mathrm{}\mathrm{cm}}^{\ensuremath{-}2}$ has been investigated using an ion-momentum imaging technique to determine the shape of the exploding molecule. The results, which are interpreted using a generalized, classical, enhanced ionization model show a range of geometries consistent with earlier measurements on ${\mathrm{CO}}_{2},$ exhibiting an enhancement of the bond angle, but no appreciable straightening. Consideration of the pre-Coulombic motion improves the agreement of our results with the enhanced ionization model, whilst revealing the presence of increased molecular bending.

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.
