Strong multiple-capture effect in slow Ar<sup>17+</sup>–Ar collisions: a quantum mechanical analysis
Bibliographic record
Abstract
A recent x-ray spectroscopy experiment on Ar17+–Ar collisions at the velocity of 0.53 au provided evidence for strong multiple electron capture (Trassinelli et al 2012 J. Phys. B: At. Mol. Opt. Phys. 45 085202). We have investigated single and multiple captures in the same system by coupling a quantum-mechanical independent electron model calculation for the collision dynamics with a phenomenological Auger model to obtain n selective capture cross sections for n = 2 to n = 10. Using these cross sections and a radiative cascade scheme, we obtained x-ray emission intensities that can be compared with the experimental data. Good agreement is found for the Lyman series from n = 3 to n = 7 if the multiple capture contributions are included, whereas calculations that ignore them are in stark conflict with the measurements.

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.
