Abstract
The hyperfine-induced 4s4p 3 P 0,2 –4s 2 1 S 0 transition rates for Zn-like ions with Z = 30–66 are calculated using a large scale relativistic configuration-interaction method. Comparisons are made between different approaches to hyperfine quenching studies, and discussions are given to the significance of various contributions. For the 3 P 0 state, the effect of the 1 P 1 state on hyperfine quenching is found to be quite substantial and cannot be ignored in spite of the large energy separation. For the 3 P 2 state, hyperfine quenching leads to different decay rates to the ground state for different hyperfine levels and the induced decays can dominated over the unperturbed M2 transition. The present results are compared with the other theoretical predictions, and reasons for the discrepancies are discussed.

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.
