Abstract
Multiple scattering has been well recognized as an important correction in neutron scattering cross-section measurements. The GEANT4 simulation toolkit includes a special thermal neutron scattering model and a corresponding data library at low neutron energies (<4 eV). A new method using GEANT4 to estimate the multiple-scattering effect in thermal neutron scattering experiments is presented. The method was applied to the double differential cross-section measurements of light water with various sample thicknesses under ambient conditions of temperature and pressure. The resulting scattering law for neutron energy transfer from 42.0 to 14.6 meV over scattering angles from 10° to 110° is presented and compared with the tabulated Evaluated Nuclear Data File (ENDF/B-VII).

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 it
