Neutron stability in nuclei
While the free neutron is unstable (half-life approx 10 min via A-sector beta decay), neutrons bound in nuclei are stable because nuclear binding energy lowers the effective mass below the decay threshold; full analysis requires the hadron classification of Part VII.

Claim boundary
This page reports a Registry-backed internal result surface. It is not an external validation claim, a scientific consensus claim, or independent acceptance.
Curation rationale
- physics-facing terms: energy, mass, neutron
- result-facing terms: bound
- candidate is better handled as evidence for an inferred existing public surface
