We report on aspects of the physics program with polarized electrons and polarized few-body systems in Amsterdam. Specifically, we focus on the first measurement of spin-correlation parameters in quasifree electron scattering from vector-polarized deuterium. Polarized electrons were injected into the AmPS electron storage ring at a beam energy of 720 MeV. A Siberian snake was employed to preserve longitudinal polarization at the interaction point. Vector-polarized deuterium was produced by an atomic beam source and injected into an open-ended cylindrical cell, internal to the electron storage ring. Spin correlation parameters were measured for the (e,e'p) and (e,e'n) reactions at a four-momentum transfer squared of 0.21 (GeV/c){sup 2}. The (e,e'p) data give detailed information about the spin structure of the deuteron, and are in fair agreement with the results of microscopic calculations that include various spin-dependent reaction mechanism effects. The (e,e'n ) data provide new information on the charge form factor of the neutron.
