Effects of incident ions energy on the asymmetry of spin polarized auger electrons

الملخص EN

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.
