Abstract
Electron impact has long been used1 to study the angular distribution of Auger electrons resulting from the electron rearrangement consecutive to an intermediate or inner shell ionization. In the case of an inner shell vacancy (nlj) with quantum number j>1/2, caused by impact ionization of a directed and unpolarized electron beam, the ion in general is left in a non-isotropic state. This anisotropy, or alignment of the ion, shows up in the anisotropy of the angular distribution of the decay products, namely the emitted x-ray photon or Auger electron.

An additional argument is that the intensities of the L3 M23 M23(3P012) and L3 М2З M23 (1S0) lines were found to be in the same ratio as the observed coincidence rates between the scattered electron and each of these lines. This indicated that the background intensity under the Auger lines did not contribute significantly to the coincidence signal.
