Coincidence measurements between electrons from projectile autoionization and target ions in specific charge states

For Ar9+ collisions on Ar we have - by means of a coincidence method - identified the number of primarily transferred electrons leading eventually to the emission of projectile Auger electrons at various energies. Auger cascades are found to play an important role: most of the high energy electrons are produced via secondary Auger processes in the last step of a cascade.
