Abstract

Cross sections for the emission of Auger electrons from excited atoms and ions produced in symmetric Ar⁺-Ar and Ne⁺-Ne collisions have been measured at ion energies from 50 to 300 keV. A simple model is proposed to explain the dependence of the cross section on the impact energy; the predicted results agree well with the experiment. Also, the argon x-ray data of Saris and Onderdelinden are compared with the model and with the results of this experiment.
