Experiments with the focal plane polarimeter at Bates
- Massachusetts Institute of Technology, Cambridge, MA (United States)
Recently, measurements of coincidence (e,e{prime}p) reactions with proton, deuteron, and carbon targets were made at the Bates Linear Accelerator Center using a newly constructed proton focal plane polarimeter. The initial measurements were of the spin transfer coefficients in elastic scattering of polarized electrons from hydrogen and in quasielastic scattering from the deuteron. Preliminary analysis indicates that, in quasifree kinematics, the spin transfer coefficients on deuterium are consistent with those on hydrogen at the few percent level. All three components of the proton polarization appear consistent with modern two-body theory. We have also completed recoil polarization measurements on the deuteron away from quasifree kinematics where the influence of other amplitudes may be enhanced. In addition, with all unpolarized beam we have measured the induced proton polarization with a carbon target and the normal component to the proton polarization at the Delta kinematics with a proton target. Measurements of the beam helicity dependent polarization components at the Delta kinematics are planned for the future.
