Recent results on spin dependent electron scattering in Amsterdam

Aspects of the physics program with polarized electrons and polarized few-body systems with AmPS in Amsterdam are presented. Specifically, we focus on the first measurement of spin-correlation parameters in quasifree electron scattering from vector-polarized deuterium. Polarized electrons were injected into an 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. The spin correlation parameter AedV was measured for the reactions 2H-vector(e-vector, e'p)n and 2H-vector(e-vector, e'n)p at a four-momentum transfer squared of 0.21 (GeV/c)2 from which new information on the spin structure of the deuteron and a value for the charge form factor of the neutron was extracted.
