Abstract

Measurements of the spin-dependent asymmetry in scattering longitudinally polarized electrons from polarized He-3 at quasielastic kinematics are reported. The measurements were made at two kinematics and spin angles, one sensitive to the helicity-dependent transverse-longitudinal interference response function, R(TL''), and the other to the helicity-dependent transverse response function, R(T''). For the experiment a metastability exchange optically pumped polarized He-3 target was used; a general discussion of the technique used to polarize the He-3, along with the details of the design and operation of the target system, are presented here. A comparison is made of the world''s data on the He-3 over arrow pointing right(e over arrow pointing right, e'') quasielastic asymmetry with several theoretical predictions, including calculations that use the plane wave impulse approximation and a fully spin-dependent spectral function. There is good agreement between data and theory at the current level of experimental precision.
