Measurement of hyperfine structure and isotope shifts in Nd II
Bibliographic record
Abstract
The high-resolution spectra of 110 transitions in Nd II over the range 418465 nm were observed using the collinear fast-ion-beam/laser method (FIBLAS). The lower states of these transitions include the ground state and 10 metastable even-parity states with energies up to 5986 cm 1 . The 64 odd-parity upper states have energies up to 29 434 cm 1 . For each transition isotope shifts were measured for all the stable isotopes (mass numbers 142, 143, 144, 145, 146, 148, and 150), as well as hyperfine parameters for the two odd-mass-number isotopes. These quantities are important in modeling profiles of absorption lines in stellar atmospheres to obtain abundances, and in the classification of atomic energy levels.

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.
