Abstracts
The class of Feynman diagrams contributing to π N → N π π which have a single pion exchange, exhibit a pole at the (unphysical) value of the momentum transfer Δ2 = -μ2. It is shown how the residue at this pole determines the π π scattering cross section. Assuming other terms do not interfere too badly, this residue should be detectable at high energy scattering with small nucleon recoil. (Science Abstracts, 1959, 546. J. C. Taylor).
