OSTI ID:801494
The recently completed experiment E94-010 at Jefferson Lab studies the neutron spin structure functions at low momentum transfer (Q{sup 2}) values. Using a polarized {sup 3} He target and polarized electron beam, we have measured the asymmetries and cross sections for {sup 3}He(e,e') from the elastic to the deep inelastic region. The covered Q{sup 2} ranges from 0.03 to 1.1 GeV{sup 2}. From the data, the Q{sup 2} evolution of the spin structure functions for {sup 3}He and neutron, and of the Gerasimov-Drell-Hearn (GDH) sum rule has been studied, and the preliminary results are presented.
