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, 5d9nd 5/2[½]1, 5d9nd 5/2[3/2]1,2, 5d9nd 5/2[5/2]2,3, 5d9nd 5/2[7/2]3 and 5d9ns 5/2[5/2]2,3, and three Rydberg series of yttrium, 5s2nd 2D3/2, 5s2nd 2D5/2 and 5s2ns 2S1/2, converging to the ground states of Pt+ (5d9 2D5/2) and Y+ (5s2 1S0), respectively, have been observed and analysed. The first ionization potentials of platinum and yttrium atoms have been determined to be IPPt = 72 257.8±0.8 cm-1 and IPY = 50 146.6±0.8 cm-1, respectively. Several unidentified lines in the spectrum of yttrium have also been observed.

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.
