Nuclear Fission as a Correlation-Access Cliff: A Minimal Diagnostic Framework

Nuclear Fission as a Correlation-Access Cliff: A Minimal Diagnostic Framework Version 1.1 — January 5, 2026 What's New in v1.1 This version adds a concise manuscript (4 pages) and digitized evidence section. Digitized HFB data (Gogny D1S) for neck parameter and pairing gap are combined into an EDF-consistent, cross-nucleus illustrative composite. Data Sources Quantity Nucleus Source Reference Neck parameter Q_N ²⁵⁸No Han et al. (2021) Phys. Rev. C 104, 064603 Pairing gap Δ ²⁶²Rf Zdeb et al. (2025) arXiv:2412.08431 Key Result The structural coherence metric κ̂fiss = Δ̃ × C̃neck decreases from ~0.81 to ~0.49 as deformation increases toward scission, consistent with the correlation-access cliff framework. Important Notes This version demonstrates feasibility only and supplements v1.0 All numerical values are digitized from published figures; no new HFB calculations are performed Data come from different nuclei (cross-nucleus composite) Package Contents paper/ — Manuscript (LaTeX + PDF) data/ — Digitized CSV files with full provenance figures/ — Publication-quality figures (PNG + PDF) code/ — Figure generation script (Python) License CC BY 4.0
