Abstract/Summary:
Elastic electromagnetic form factors of the nucleon are of fundamental importance for our understanding of its internal structure. Experiment E93-026 at the Thomas Jefferson National Accelerator Facility (JLab) determined the electric form factor of the neutron, GnE , through quasielastic d&ar;e&ar; ,enp scattering using a longitudinally polarized electron beam and a frozen polarized 15ND3 target. The knocked out neutrons were detected in a segmented plastic scintillator detector in coincidence with the scattered electrons. The form factor was extracted by comparing the experimental beam-target asymmetry with full theoretical calculations based on different values of GnE . The dissertation discusses the experimental setup, data acquisition and analysis for the Q2 = 1.0 (GeV/c)2 point, and implications of the experimental results for our understanding of the nucleon electromagnetic structure.
