Abstract
The Jefferson Lab (JLab) Hall A E97110 experiment performed a precise measurement of the
neutron spin structure functions at low Q2 by using a polarized 3He target as an effective polarized neutron target. The goals of the experiment are to make a bench-mark test of Chiral Perturbation Theory calculations and to check the Gerasimov-Drell-Hearn (GDH) sum rule by extrapolating the integral to the real photon point. The data were taken in two experimental run periods. The first period covered the lowest Q2 points but with a defective equipment which complicates the data analysis. The second period covered higher Q2 point, with a properly working equipment. Preliminary results from second period will be discussed. The spin structure functions g1 and g2, and the spin-dependent partial cross section sTT of 3He and neutron will be discussed.
