摘要：

The photopion production of He-3(gamma, pi+)H-3 has been calculated by the distorted-wave impulse approximation in order to include the final state interaction (FSI) between pi+ and H-3. The optical potentials used to describe the FSI are the Stricker, McManus, and Carr potential and the Kim potential. The inclusion of the FSI improves significantly the theoretical estimations compared with the results of plane-wave impulse approximation. In case of low momentum transfer the contribution of E1+(3/2) amplitude is shown to play an additional role in obtaining an agreement with the experimental results.
