Geometric Origin of the Strong Nuclear Force: Lattice Pinning Strength and the Iron Stability Peak

We derive the nuclear stability scale directly from Kim's Isotropic Template (KIT) without any independent coupling constants. The strong nuclear force is interpreted as a topological "lattice pinning" effect, where nucleons are trapped in potential wells formed by the trivial zeros of the Riemann zeta function. Our numerical analysis yields a Lattice Pinning Strength (S₋₏) of approximately 7. 93 MeV, matching the empirical energy per nucleon. We further demonstrate that S₋₏ reaches its absolute maximum at ^56Fe, providing a parameter-free geometric explanation for the iron stability peak and a resolution to the Strong CP problem via real-axis phase-locking.
