The experiment E94010 at Jefferson Lab: The study of the neutron spin structure and connection between GDH and Bjorken Sums Rules Session LB11 - Minisymposium on the Structure of the Nucleon I.
FOCUS session, Tuesday afternoon, March 23 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 øverrightarrow^3He(øverrightarrowe,e') to
study the nuclear medium effect. On-line results will be presented.
