Charge transfer and ionization in collisions of O<sup>8+</sup> ions with excited He atoms
Bibliographic record
Abstract
Two-centre atomic orbital close-coupling calculations are carried out for the cross sections of single electron capture and single ionization in O 8+ + He(1s1s) and O 8+ + He(1s3d) collisions in the velocity range from 0.6 to 2.0 a.u. The relative importance of single ionization to single capture are investigated for both systems. Our calculations are in good agreement with experimental data of O 8+ + He(1s1s) collision. The ratio curves also show us distinct behavior between the two collision systems. The partial electron capture cross sections for O 8+ + He(1s3d) collision indicate that, corresponding with the astrophysical conclusion, most of the l-levels are populated statistically for energies greater than 10 keV, and some distributions of lower n at low collision energy show a trend close to the binomial distribution.

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.
