These spectra contain intensive satellite structure below the bottom of the valence band which is due to both the electron correlation in the target and the instrumental multiple scattering effect. We use the Monte Carlo procedure to simulate the multiple scattering and employ various realistic models to describe the many-electron correlation in the aluminum crystal
