| 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. |
| Keywords: | GDH sum rule dilution factor correction cross section asymmetry |
