"Analysis on the Target Polarization for the study of the GDH Integral on the Deuteron Target"
The EG4 experiment at the Jefferson Lab (E12-06-109) studied the GDH (Gerasimov-Drell_Hearn) Sum Rule that relates the difference of the two photoabsorption cross-sections to the anomalous magnetic moment of the proton, deuteron and neutron in the real photon limit. In reality we try to approach the real photon limit by having the Q 2 very small. The experiment used a highly polarized electron beam and longitudinally polarized solid ammonia targets. The analysis to determine the deuteron target polarization using the data acquired from the NMR system will be shown with different analysis methods compared and further target polarization analysis via the scattering asymmetry method is also discussed.
