The usual field theory of spin 0 nucleons coupled to vecter mesons (or heavy photons) is studied in order to find out whether the nucleon lies on a Regge trajectory. Photonnucleon scattering is examined, to each order in the coupling constant, with the highest power of ln cos theta retained. It ig found that a suitable Regge trajectory is generated, but tuat the nucleon does not lie on it. The nucleon pole term in the scattering amplitude corresponds to a fixed singularity in angular momentum. The spin 0 nucleon thus behaves differently from a particle of spin. (auth)
