| Abstract: | Coherent  0 and + photoproduction and elastic and charge-exchange pion scattering on3He 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 as3He( , 0)3He(0, +)3H 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 has been removed.Supported by the Deutsche Forschungsgemeinschaft (SFB 201) |
