Revised and extended analysis of the spectrum of ten-times-ionized cerium (Ce XI)
Bibliographic record
Abstract
Cerium spectra were recorded in the 100–1240-Å region by use of laser-produced plasma and triggered spark sources. An earlier analysis of Ce xi was almost completely revised. In the even-parity system we established 31 levels belonging to the 5s2,5p2,5s5d,5s6s,4f5p, and 4f2 configuration, of which 28 are new levels. In the odd-parity system we established 36 levels, 31 of them new, belonging to the 5s5p,5p5d,4f5s,5s5f, and 5s6p configurations. The 4f2 and 4f5d configurations have been identified in the Cd i isoelectronic sequence for the first time to our knowledge. One hundred twenty-four lines have been classified in Ce xi. Hartree–Fock and least-squares-fitting calculations were carried out, and they represent the observed spectrum satisfactorily. The ionization potential of the Ce xi ion has been estimated to be 1 468 150±100 cm-1(181.99±0.01 eV).

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.
