Abstract：

In the GDH sum rule measurement in JLab Hall-A, to obtain the cross section of electron scattering on polarized³He and its asymmetry in different helicity states, the dilution effect from unpolarized nitrogen mixed in the polarized³He target were calculated at different kinematic settings.
