Full binding energy accuracy table. V4 predictions vs AME2020 experimental values across all 116 elements. Mean error ~1%, systematic accuracy of the CPT nuclear framework.
Overview
The V4 Nuclear Binding Engine computes nuclear binding energies for all stable nuclides based strictly on the geometric constraints of the CPT framework.
Calibration relies on exactly two points: the deuteron ( MeV) and the alpha-particle ( MeV). These fix the EM coupling scale and nuclear radius parameter. All other predictions have modelled package.
Validation Methodology
V4 predictions are compared directly against the AME2020 (Atomic Mass Evaluation 2020) values. We report the residual error as:

Status: Established Tool
The full 116-element table is available via the V4 engine at /software/v4-nuclear-engine. The engine systematically outputs the full table on demand, proving the large-scale applicability of the geometric binding rules.
