| Publication Abstract: | The neutron electric form factor, GEN , is extracted for the first time at Q^2 = 1 (GeV/c)^2 from polarized 3He(pol.e ,e ?) measurements in Hall A at Jefferson Lab. By getting the ratio of asymmetries in longitudinal and transverse quasi-elastic pol. He(pol. e ,e ' ), the electric and magnetic contributions can be separated. The proton and neutron contributions to the 3 He quasi-elastic response functions are calculated in PWIA by Salme? et al., and the neutron electric form factor can be extracted. This method of inclusive scattering becomes feasible for the first time due to the falloff of the other form factors at high Q^2 while GEN keeps increasing in units of the dipole form factor. Approximately, 20% uncertainty is achieved in the extraction largely contributed by the statistical uncertainties from 3 days of data-taking. All aspects of the measurement will be discussed in this thesis including theoretical model, experiment setup and the details in the analysis. | ||
