Title A Precision Measurement of the Transverse Asymmetry A_T' from Quasi-elastic ^3He(e,e¿) process, and the Neutron Magnetic Form Factor GNM at low Q^2
Abstract Electromagnetic form factors are fundamental quantities in describing the underlying electromagnetci structure of nucleons.While proton electromagnetic form factors have been determined with good precision, neutron form factors are known poorly, largely due to the lack of free neutron targets.Jefferson Lab Hall A experiment E95-001, a "precise measurement of the transverse asymmetry A_T' from the quasielastic ^3{polarized}He({polarized}e, e') process," was therefore designed to determine precisely the neutron magnetic form factor, G^n_M at low momentum transfer values and was successsfully completed in Spring 1999.High precision A_T'data in the quasi-elastic region at Q^2 values of 0.1 to 0.6 (GeV/c)^2 were obtained using a high-pressure spin-exchange optically-pumped polarized ^3He gas target with an average polarization of 30%, a longitudinally polarized e^- beam, and two High Resolution Spectrometers: HRSe and HRSh.HRSe was employed to detect scattered electrons
