High-spin inner-shell excited states in few-electron neon: quintets and sextets
Bibliographic record
Abstract
Quintet states in Be-like Ne VII and sextet states in B-like Ne VI have been investigated by beam-foil spectroscopy in the XUV spectral region. The wavelengths of the n = 2- n ' = 3 transitions from the inner-shell excited terms 1s2 l 2 pn ' l ' 5 L ; l = s,p; l ' = s,p,d and 1s2l2p 2 n ' l ' 6 L ; l = s,p; l ' = s,p,d are obtained using Hartree-Fock calculations and linear Z -expansions in the respective isoelectronic sequences. Lifetime measurements are presented for some n = 3 quintet levels. Spectral lines are assigned to n = 2- n ' = 4 transitions supported by 32 new line identifications in Ne VI, VII and IX. A class of metastable low-spin inner-shell excited states in Be-like ions, possible candidates for XUV-laser schemes, are also discussed. Finally, metastable 3 l 3 l ' sextet states in the B sequence are introduced, one of which might be bound in Be - .

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.
