摘要：

Coherent pi-0 and pi+ photoproduction and elastic and charge-exchange pion scattering on He-3 has ben calculated in a consistent model. Realistic three-body Faddeev wave functions have been used and full nonlocal DWIA results for pion photoproduction are obtained. Furthermore, two-step processes such as He-3(gamma,pi-0)He-3(pi-0,pi+)H-3 are included giving rise to unexpected large results. The comparison with experimental data is very good over a wide range of photon energies and nuclear momentum transfers. A long-time discrepancy between previous impulse-approximation calculations and experimental data ha been removed.
