Computational Checkpoints for a Candidate Collective Three-Nucleon Interaction charles konkle (22076399) Nuclear physics three-nucleon interaction Faddeev equations triton binding energy nuclear few-body physics three-body force spin-angular projection computational nuclear physics Baryonic Matter Physics <p dir="ltr">This dataset documents computational tests of a candidate collective three-nucleon interaction in a five-channel Faddeev framework. The locked pair-only hydrogen-3 calculation reproduces 7.1883 MeV. Tests corrected errors involving quadrature weights, angular projection, permutation maps and mapped-grid Hankel transforms. The proposed additional interaction is not yet validated: its independent coordinate-space reference and production-grid stability remain incomplete. The provisional coupling was rejected as a numerical artifact. No coupling constant is frozen and no helium-3 prediction is reported. This checkpoint is provided for reproducibility, continued development and independent specialist review.</p> 2026-09-15T05:38:07Z Dataset Dataset 10.6084/m9.figshare.33771391.v1 https://figshare.com/articles/dataset/Computational_Checkpoints_for_a_Candidate_Collective_Three-Nucleon_Interaction/33771391 CC BY 4.0
