摘要：

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-degrees, 45-degrees, and 120-degrees at fluences in the range of 2 x 10(13) to 4 x 10(15) 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.
