Neutron Spin Structure Study at Jefferson Lab Hall A

PDF Version Also Available for Download.

Description

With a high-intensity highly-polarized 6 GeV electron beam, and a high-density polarized {sup 3}He target, we have carried out a number of experiments to study the neutron spin structure at Hall A in Jefferson Lab. Taking advantage of the high luminosity of Jefferson Lab, we completed two inclusive deep-inelastic-scattering experiments this summer. In the first, precision measurements were made of the spin asymmetry A{sup n}{sub 1} in the valence quark (high Bjorken x) region; and in the second, higher-twist effects were studied via precision measurements of g{sup n}{sub 2}. Physics motivation and preliminary results from the first experiment will be ... continued below

Taking advantage of the high luminosity of Jefferson Lab, we completed two inclusive deep-inelastic-scattering experiments this summer.

Physics motivation and preliminary results from the first experiment will be presented and discussed. I will also present nearly final results from an earlier experiment, which measured the generalized GDH sum for the neutron in the Q{sup 2} range of 0.1 to 1 GeV{sup 2}. Planned near-term experiments will be briefly discussed.
