摘要：

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