"Experimental study of the 3He and neutron spin structure at low Q2 using a polarized 3He target"
 Slideshow (PDF)

I will report on the analysis status of the Jefferson Lab (JLab) Hall A E97110 experiment. The 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 complicate the data analysis. The second period covered higher Q2 point, with a properly working equipment. The raw asymmetry analysis and elastic carbon cross section measurement will be discussed for the fi run period along with the future plans for the analysis. I will also discuss the progress and the tests in the polarized 3He Target Lab at JLab. Results of Pulse NMR (nuclear magnetic resonance) will be presented.
