F. S A C C H E T T I
Dipartimento di Fisica dell'Universit~ di Perugia, 1-06100 Perugia, Italy Received 29 April 1988; accepted for publication 26 October 1988 A simple and efficient method to deduce the true Auger spectrum from the raw data is presented. This method is an application to Auger spectroscopy derived from signal processing procedures employed in different fields. It appears particularly promising when complex spectra are analyzed as it avoids spurious information to be introduced. The method is also compared with the more-standard van Cittert's approach. An experimental check of the c o m m o n assumption that an Auger electron experiences almost the same energy-loss mechanisms as a nearly elastically reflected primary electron at the same energy is given.
