Abstract
Further evidence is presented for the violation of causality in the Compton scattering of light by protons for the energy region near the Δ(1232) resonance. A very simple precausal model has been found to reproduce both the photon absorption and scattering cross sections. Since dispersion relations are significantly violated in the same energy region, it is concluded that no causal model can fit the data as well as the precausal model.
