Abstract

Typically, enhanced intensities are observed along low-index crystallographic directions of the crystal when Auger or photoelectrons with a kinetic energy of several hundred eV or more are emitted from atoms in a solid. This effect is a result of strong forward scattering of emitted electrons by overlying lattice atoms. Contrary to this image, a strong dip along the [110] direction has been found in the angular distribution curve of O-KLL Auger electrons of the MgO(001) surface, even though the kinetic energy of O-KLL Auger electrons is about 500 eV. The angular dependence of Auger (O-KLL, Mg-KLL) and photoelectrons (O1s) in MgO(001) is discussed and explained within a multiple scattering cluster model, respectively.
