Abstract
A semi-empirical method is used to characterize the 3s 2 3p 2 –3s3p 3 J = 2 transition array in P II. In this method Slater, spin–orbit, and radial parameters are fitted to experimental energy levels to obtain a description of the array in terms of LS-coupling basis vectors. The intermediate coupling (IC) and configuration interaction (CI) amplitudes so obtained are then used to predict the branching fractions of transitions within the array. These two configurations are particularly interesting because the 3s 2 3p 2 has been shown to be virtually free of CI, but affected by IC, whereas the 3s3p 3 is virtually free of IC, but affected by CI.

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.
