In this study a multiple scattering theory of ionization of hydrogen atoms is used. The latest results of the present method are compared with other calculations.

In addition image charge final state electron surface interactions have been initiated in the relativistic region as well as the scattering of the projectile from the multi-center bulk potential. Finally, a semi-relativistic condition is considered in place of the ionization mechanism of scattering from an aluminium semi-infinite solid target by non-relativistic electrons to determine multiple differential cross-section.展开更多
