摘要：

We have calculated the angular distribution functions for Auger electrons emitted from Be-like Mg, Fe, and Mo following 1s-2p excitation by electron impact. The calculations were carried out in intermediate coupling with configuration interaction using the relativistic distorted-wave and multiconfiguration Dirac-Fock methods. We found strong angular asymmetry for many transitions. We also found that relativistic effects can completely change the characteristics of the angular distribution for transitions which have many contributing partial waves, even for ions as light as Fe.
