Rydberg series and the first ionization potential of platinum and yttrium atoms
Bibliographic record
Abstract
Rydberg spectra of platinum and yttrium atoms have been studied by the atomic beam double-resonance pulsed-field ionization detection technique. Five Rydberg series of platinum, 5d 9 n d 5 / 2 [½] 1 , 5d 9 n d 5 / 2 [ 3 / 2 ] 1,2 , 5d 9 n d 5 / 2 [ 5 / 2 ] 2,3 , 5d 9 n d 5 / 2 [ 7 / 2 ] 3 and 5d 9 n s 5 / 2 [ 5 / 2 ] 2,3 , and three Rydberg series of yttrium, 5s 2 n d 2 D 3/2 , 5s 2 n d 2 D 5/2 and 5s 2 n s 2 S 1/2 , converging to the ground states of Pt + (5d 9 2 D 5/2 ) and Y + (5s 2 1 S 0 ), respectively, have been observed and analysed. The first ionization potentials of platinum and yttrium atoms have been determined to be IP Pt = 72 257.8±0.8 cm -1 and IP Y = 50 146.6±0.8 cm -1 , respectively. Several unidentified lines in the spectrum of yttrium have also been observed.

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.
