The experiment E94010 at Jefferson Lab: the study of the neutron spin structure and connection between GDH and Bjorken Sums Rules

Abstract : Session LB11 - Minisymposium on the Structure of the Nucleon I. FOCUS session, Tuesday afternoon, March 23 Room 218E, GWCC [LB11.04] The experiment E94010 at Jefferson Lab: The study of the neutron spin structure and connection between GDH and Bjorken Sums Rules Alexandre Deur (Jefferson Lab and LPC: universite Blaise Pascal/in2p3), E94010 Collaboration We have recently completed Hall A Jefferson Lab experiment E94010.The experiment studies the neutron spin structure and the Q^2 evolution of the GDH and Bjorken Sum Rules.Using a polarized ^3He target and polarized beam, the virtual photon-neutron asymmetry A(_1^n\nu,Q^2) and the spin structure function g_1^n has been measured from the pion threshold to the deep-inelastic region. The Q^2 range covered is from 0.2 to 1 GeV^2. Asymmetries and cross sections have also been measured for the quasi-elastic \overrightarrow{^3He}(\overrightarrow{e},e') to study the nuclear medium effect. On-line results will be presented.
