摘要：

New backward scattering data on γp → π0p and γp → π+n are fitted with Nα, Nγ and Δδ Regge exchanges. We find an Nα - Nγ trajectory degeneracy and residues β (Nγ) ≈ 0.6 β (Nα). The Δδ exchange amplitude dominates at large u, while the Nα - Nγ contribution plays a prominent role at small u. © 1969.
