| Abstract: | The conception of generalized Stokes parameters and their measurement method are introduced. It is effective to describe the excited atom states impacted by spin-polarized electrons through analyzing these parameters, which may not only obtain more information of excited state, but also show the dynamic process of spin-polarized electron colliding with atom. |
