Interatomic forces over a wide range of nuclear separations
Bibliographic record
Abstract
An interaction potential energy between rare gas atoms is set up which: (1) Reproduces the correct angular distribution for atomic scattering at high energies. (2) Fits the second virial coefficient and molecular orbital calculations at the smallest separations yet considered. (3) Fits the quantum mechanically calculated van der Waals constant. The most careful calculations we report are for Ne-Ne interactions. The gas scattering data in the high energy regime (25-100 kev) is shown to be fitted, to within experimental error, by either the Bohr or the Firsov potentials. This analysis gives information on the potential inside half a Bohr radius a0. The smallest distance at which molecular orbital calculations are available for Ne-Ne, on the other hand, is 2.5a0. A potential constructed by joining together forms appropriate for small and large nuclear separations is then used in molecular dynamical calculations of the liquid structure factor. The main features can be satisfactorily reproduced by a potential resembling a Lennard-Jones potential in the bowl, but joining on to a much softer potential at small distances. Finally, some remarks are made on the change in the two-body potential at large distances, in condensed matter, from that between rare gas atoms in a vacuum and the major differences for metal atom (eg. Li) interactions are stressed.

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.
