This study focuses on the angular and the energy dependence of the exchange scattering between an energetic polarized electron and the conduction band electrons of an itinerant ferromagnet. Upon the collisions the two electrons participating in the scattering process are excited into vacuum levels where their quantum mechanical states, i.e. their wave vectors can be resolved at the same time. The numerical calculations illustrate that the recorded two-particle spectra can be utilized to study the spin-split electronic structure near the Fermi level and to obtain information on the nature of the exchange scattering in ferromagnetic materials.
