Abstract

fetched live from OpenAlex

A general formalism is used to express the long-range potential energies in inverse powers of the separation distance between two like atomic or molecular systems with $P$ symmetries. The long-range molecular interaction coefficients are calculated for the molecular symmetries $\ensuremath{\Delta}$, $\ensuremath{\Pi}$, and $\ensuremath{\Sigma}$, arising from the following interactions: $\mathrm{He}(2\phantom{\rule{0.2em}{0ex}}^{1}P)--\mathrm{He}(2\phantom{\rule{0.2em}{0ex}}^{1}P)$, $\mathrm{He}(2\phantom{\rule{0.2em}{0ex}}^{1}P)--\mathrm{He}(2\phantom{\rule{0.2em}{0ex}}^{3}P)$, and $\mathrm{He}(2\phantom{\rule{0.2em}{0ex}}^{3}P)--\mathrm{He}(2\phantom{\rule{0.2em}{0ex}}^{3}P)$. The electric quadrupole-quadrupole term ${C}_{5}$, the van der Waals (dispersion) term ${C}_{6}$, and higher-order terms ${C}_{8}$ and ${C}_{10}$ are calculated ab initio using accurate variational wave functions in Hylleraas coordinates with finite nuclear mass effects. A comparison is made with previously published results where available.

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.
