Electron impact excitation rates for transitions in Mg V
Bibliographic record
Abstract
Energy levels, radiative rates (A-values), and lifetimes, calculated with the GRASP code, are reported for an astrophysically important O-like ion, Mg V. Results are presented for transitions among the lowest 86 levels belonging to the 2s 2 2p 4 , 2s2p 5 , 2p 6 , and 2s 2 2p 3 3[Formula: see text] configurations. There is satisfactory agreement with earlier data for most levels and transitions, but scope remains for improvement. Collision strengths are also calculated, with the DARC code, and the results obtained are comparable for most transitions (at energies above thresholds) with earlier work using the DW code. In the threshold region, resonances have been resolved in a fine energy mesh to determine values of effective collision strengths (Υ) as accurately as possible. Results are reported for all transitions at temperatures up to 10 6 K, which should be sufficient for most astrophysical applications. However, a comparison with earlier data reveals discrepancies of up to two orders of magnitude for over 60% of transitions, at all temperatures. The reasons for these discrepancies are discussed in detail.

How this classification was reachedexpand
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.
