• GDH sum rule
• dilution factor
• correction
• cross section
• asymmetry

In the GDH sum rule measurement in JLab Hall-A, to obtain the cross section of electron scattering on polarized 3 He and its asymmetry in different helicity states, the dilution effect from unpolarized nitrogen mixed in the polarized He-3 target were calculated at different kinematic settings.
