摘要：
An experiment to measure elastic electron scattering off He-3 and He-4 at large momentum transfers is presented. The experiment was carried out in the Hall A Facility of Jefferson Lab. Elastic electron scattering off He-3 was measured at forward and backward electron scattering angles to extract the isotope's charge and magnetic form factors. The charge form factor of 4He will be extracted from forward-angle electron scattering angle measurements. The data are expected to significantly extend and improve the existing measurements of the three- and four-body form factors. The results will be crucial for the establishment of a canonical standard model for the few-body nuclear systems and for testing predictions of quark dimensional scaling and hybrid nucleon-quark models.
