## Statement

In the registered two-alpha channel, no leading bridge is typeable; B(8Be) = 2Bα at leading order, and the first annular correction has Sαα = −ϕ⁻¹⁸√σ < 0.

## Caution

This channel result does not give a complete nuclear Hamiltonian or settle the separate charge and breathing-accounting problems.

## Primary source

Paper 9, §4, Theorem 4.2: leading two-alpha relation, PDF p.132: "α ⊗ α = 1 ⊗ 1 exposes no τ -line: no bridge is typeable, B(8 Be) = 2Bα √ at leading order"
