Abstract

Within the hamiltonian model of Nozawa, Blankleider and Lee, the meson exchange πN model developed by Pearce and Jennings is used to calculate the effects of the πN final-state interaction on the γN → πN reaction. It is found that the results for charged pion production processes are comparable to that of earlier calculations using separable πN models. The main improvement is a much better description of the neutral pion production process from threshold to about 400 MeV incident photon energy.
