Abstract
Abstract We theoretically investigate the doubly excited 1 P o resonance series of the O 6+ ion converging towards the N = 3 threshold. No experimental measurements of the energy positions E and the widths Γ for the states belonging to the different series have been reported so far. On the theoretical side, the existing results are rare and not in a perfect agreement. We report in this work accurate results of the resonant parameters ( E , Γ) for the 1 P o resonance states of the ion obtained by using a B -spline based spectral approach combined with the complex rotation method. Our method has the numerical advantage to generate the resonant parameters in a single calculation. It also allows the identification of the states that share similar angular correlation pattern, which helps in their classification into distinct series. Results of the resonant parameters for the high-lying 1 P o states are being reported for the first time.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
