Nonresonant multiphoton excitation spectra of atomic <sup>7</sup>Li
Bibliographic record
Abstract
The nonresonant multiphoton laser-induced fluorescence excitation spectrum of isotopically purified 7 Li was obtained with a tunable, pulsed, nanosecond laser scanned between 13 600 and 14 500 cm 1 . The measured Rydberg series include n 2 P [Formula: see text] 2 2 S, n 2 F [Formula: see text] 2 2 S, n 2 P [Formula: see text]2 2 P, and n 2 F [Formula: see text] 2 2 P, and term values up to 14 2 P and 28 2 F were determined. Features due to the ac Stark effect become prominent for the high Rydberg states, but can be eliminated by using circular instead of plane-polarized radiation. Quantum defect values for the n 2 P, n 2 D, and n 2 F levels were determined. Those for the n 2 F states cover a range of principal quantum numbers not previously investigated. PACS Nos.: 32.80Rm, 32.30Jc, 32.70Jz

How this classification was reachedexpand
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.
