Effects of Incident Ions Energy on the Asymmetry of Spin Polarized Auger Electrons

Abstract

The theoretical aspects of the spin polarization of Auger electrons have been formulated in a simple model. The model allow us to explain in quantitative terms the measured spin polarization of the yield in the interaction of spin polarized He+ ions with metal surfaces.The spin polarized emitted Auger electrons can be simply related to the character of the hole state on the He+ ion.The effects of the energy of incident of the He+ ion on the emitted spin polarized electron are calculate and discussed, Our calculations to the spin polarized emitted electrons from Ni(110) , Al(100) surfaces are compared with experimental data show a good agreement.
