| Title | Precision Measurement of the Spin-dependent Asymmetry in the Threshold Region of Quasielastic 3He | ||||
| Abstract | The first precision measurement of the spin-dependent asymmetry in the threshold region of polarized ^3He(polarized e, e') was carried out in Hall A at the Jefferson Laboratory, using a longitudinally polarized continuous electron beam incident on a high-pressurepolarized ^3He gas target.The polarized electron beam was generated by illuminating a strained GaAs cathode with high intensity circularly polarized laser light, and an average beam polarization of about 70% was achieved.The ^3He target was polarized based on the principle of spin-exchange optical pumpint and the average target polarization was about 30%.The scattered electrons were detected in the two Hall A high resolution spectrometers, HRSe and HRSh.The data from HRSh were used for this analysis and covered both the elastic peak and the threshold region.Two kinematic points were measured in the threshold region, one with a central Q^2-value of 0.1 (GeV/c)^2 at an incident beam energy E_0 = 0.778 GeV and the oth | ||||
