Abstract

fetched live from OpenAlex

High level ab initio calculations carried out for the 2A′ and 2A″ states of ArNO(X 2Π) predict a crossing near the T-shape configuration, with the 2A′ minimum being slightly deeper. Spin-orbit coupling is included through a model treatment and results in two potential energy surfaces with similar topologies, nearly parallel to each other and close to the averaged non-relativistic surface. These results are used to construct a DIM-like model for Ar n NO clusters. The lowest energy cluster structures are found to resemble those for Ar n+1 with NO lying in the surface. The set of major magic numbers (structures of pronounced stability) is also the same as for the Ar n+1 clusters, and is emphasized further by the detachment of NO, which requires a larger energy than for detachment of a single Ar atom. The relations of the difference between the two dissociation energies and of the Ar n NO(1/2 → 3/2) excitation energy to the magic numbers are discussed.

Not 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.
