摘要：

Auger electron spectra from the neutralization of highly charged ions which impinge on a metal surface are influenced by ion-solid, election-ion, and electron-solid interactions. Individual as well as combination effects between these interactions are studied by means of a Monte Carlo simulation of projectile Auger electron spectra. A new mechanism in spectrum formation is identified, i.e. Doppler line broadening due to post emission elastic scattering. This effect explains some shoulders or weak satellite lines which are seen in recent measurements on both sides of the peak. Known methods of background correction can treat this effect only in special circumstances.
