Re-evaluating low-energy neutron-deuteron elastic scattering using three-nucleon theory
Bibliographic record
Abstract
Using a well-established nucleon-nucleon interaction that fits the NN scattering data (Bonn potential), and the AGS form of three-body theory, we perform precise calculations of low-energy neutron-deuteron scattering. There appear to be problems for this system in the ENDF/B-VI.8 (ENDF/B-VI.5 through VI.8) data library, which persist in the newest version, ENDF/B-VII.0. Supporting experimental data in this energy region are rather old (>25 years), sparse and often inconsistent. Our three-body results at low energies, 50 keV to 10 MeV are compared to the ENDF/B-VII.0 and JENDL-3.3 evaluated angular distributions. The impact of these results on calculated reactivity for various critical systems involving heavy water is shown.

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.
