New physics can be accessed by scattering polarized electrons from a polarized 3He internal gas target. It is discussed how the asymmetries for the reactions 3He(eqq, e′), 3He(eqq, e′p) 3He(eqq, e′n) 3He(eqq, e′d) and 3He(eqq, e′pn) may provide precise information on the S′ and the D-wave parts of the 3He ground-state wave function, the neutron form factors, and the role of spin-dependent reaction mechanism effects. The experiment uses up to 900 MeV (polarized) electrons from the AmPS storage ring in Amsterdam, Netherlands, in combination with large acceptance electron and hadron detectors.
