Abstract

fetched live from OpenAlex

A molecular jet-expansion beam of ZnNe seeded in Ne was crossed with a pulsed-laser beam produced by a Nd:YAG (yttrium aluminum garnet) laser-pumped dye laser. The dye laser was frequency doubled with a BBO-C second-harmonic-generation (SHG) crystal. Both the dye laser and the SHG were synchronously scanned over a range of $\ensuremath{\lambda}=2130--2170\AA{}$ in the vicinity of the Zn atomic $4{}^{1}{P}_{1}--4{}^{1}{S}_{0}$ resonance line (2138.65 \AA{}), producing an excitation spectrum related to the $D1(4{}^{1}{P}_{1})\ensuremath{\leftarrow}{X0}^{+}(4{}^{1}{S}_{0})$ transition in the ZnNe molecule. The spectral traces, which show a pronounced vibrational structure, were subjected to LeRoy's near-dissociation expansion (NDE) analysis, yielding ${\ensuremath{\omega}}_{e},$ ${\ensuremath{\omega}}_{e}{x}_{e},$ ${D}_{e},$ and long-range molecular potential parameters. Computer simulation of the excitation spectrum, based on a calculation of the Franck-Condon factors, yielded additional information on the equilibrium internuclear separation for the $D1$ and ${X0}^{+}$ states. The NDE analysis provided long-range characteristics for the ${X0}^{+}$ state of the CdNe and HgNe molecules as well. A simple dispersive model, and a combination rule for van der Waals interactions in the ground state of ZnNe, CdNe, and HgNe molecules, are discussed.

Full frame distilled prediction

Teacher imitation

Not 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.
