Abstract
Results gained for electron scattering on 3He in a nonrelativistic framework are reviewed. The electromagnetic current is truncated to a single nucleon operator, but the interaction among the three nucleons is treated exactly. Thus initial and final 3N states are evaluated consistently as solutions of Faddeev equations based on realistic NN forces. The correct inclusion of the final state interaction turned out to be important. The agreement to data is reasonably good, but the neglection of MEC's can be seen. That inconsistency should be removed. For pd capture processes we included some MEC's via the Siegert theorem, which dramatically improves the description of the pd capture data.
