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