Vacuum ultraviolet laser/time-of-flight mass spectra of Xe<sub>2</sub> near Xe* (5d, 6p, 6') atomic lines
Bibliographic record
Abstract
Four Rydberg state < ground-state transitions of supersonically cooled Xe 2 , in the vicinity of the Xe* (5d, 6p, 6s') manifolds, have been excited with a tunable vacuum ultraviolet (VUV) "laser" generated by four-wave mixing in Kr or Hg nonlinear media. Molecular ions produced by (1 + 1') resonance-enhanced multiphoton ionization (REMPI), and (or) atomic fragment ions resulting from excited-state predissociation followed by ionization, were mass selected in a linear time-of-flight (TOF) mass spectrometer. Vibrational analyses of two of the resultant spectra have led to excited-state molecular constants, while equilibrium bond lengths were estimated by Franck-Condon intensity simulations. Constants could be derived for a third transition but the REMPI/TOF spectra exhibit interesting intensity anomalies that prevented a bond length from being determined. The fourth system was found to be strongly perturbed. In the absence of rotational resolution, possible excited-state electronic symmetries were deduced from angular-momentum arguments. Possible reasons are presented for the observed distortions in the shapes of the Rydberg-state potential-energy curves from their expected nonbonding forms. PACS Nos.: 31.00 and 33.00

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.
