Extreme ultraviolet laser/time-of-flight mass spectra of Kr2 near Kr*(4d,5p′,6s)
Bibliographic record
Abstract
New single-photon spectra of jet-cooled Kr2 between ∼98 700 and 99 900 cm−1 have been recorded with an extreme ultraviolet laser generated by four-wave sum-mixing in Xe gas. Molecular ions created by (1+1′) resonance enhanced multiphoton ionization, and daughter atomic ions created by excited state predissociation prior to ionization were mass dispersed and detected in a time-of-flight mass spectrometer. Analyses of the subsequent single isotopic spectra have resulted in vibrational numbering and constants for eight band systems of Kr2 that dissociate to Kr(1S0)+Kr*(4d,5p′,6s). Excited state bond lengths were estimated by Franck–Condon factor intensity simulations. When possible, electronic symmetry assignments for the states were established by correlation diagrams constructed from angular momentum arguments. Possible reasons are discussed for the deviations observed for the shape of many of the observed Rydberg state potential energy curves from their expected nonbonding form.

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.
