Abstract

Angle-resolved electron intensity distributions for Auger and photo- electrons are calculated using a curved-wave electron scattering formalism and compared with experiment. The distributions are found to depend significantly on both the ℓ and mℓ quantum numbers of the scattered electron. We consider the simple metals Ir and Al. Although the intensity patterns depend strongly on the ℓ quantum number at relatively low energy, even at high energies (around 1500 eV), a significant ℓ effect remains, which we find arises from nearest neighbor single scattering and from the multiple scattering or defocussing effect. The relative contribution of each ℓ and mℓ partial wave is determined not only by the quantum mechanicaf matrix elements, but also by the energy, polarization, and direction of the excitation beam.
