Abstract

The angle, energy, and fluence dependence of electron emission following the interaction of normally incident 100-MeV Ne9+ ions with thin polypropylene foils and 170-MeV Ne7+ projectiles with Mylar foils has been investigated experimentally. Spectra were taken for electron ejection angles of 0°, 45°, and 120°at fluences in the range of 2×1013 to 4×1015 ions/cm2. A fluence-dependent carbon KLL Auger energy shift of up to 68 eV was observed. Model calculations for the nuclear track potential are consistent with the experimental findings.
