Abstract

fetched live from OpenAlex

The fragmentation of SF 6 under 15–30 keV O − and 20–30 keV Al − impact has been studied using a crossed beam technique. The recoil ions and ion pairs are identified in coincidence with scattered projectiles with different charge states by the usage of time-of-flight (TOF) mass spectroscopy. The yield ratios of fragment ions to [Formula: see text] and the yield ratios of ion pairs to (S + , F + ) in collision with O − and Al − are obtained and compared with those of H − and C − . It is found that the ratios have a very strong dependence on the momenta of the projectiles. Besides, by analyzing the TOF spectra, it is also found that more [Formula: see text] with n odd are produced than those with n even under O − , Al − impact, which also happened in collision with H − and C − , positive ion and electron impact. The dissociation channels of [Formula: see text] are found to be insensitive to incident ions’ energy and kind in our energy range.

Teacher imitation

Not 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.
