Abstract
Absolute doubly differential electron emission yields have been measured for high energy Ne-ions (3.5 to 8.5 MeV/u) penetrating C-foils of thicknesses between 5 and 100 μg/cm2 under normal incidence. Spectra were obtained for electron energies from 10 eV to 6 keV and electron ejection angles ranging from 0° to 180°. Results of a new theoretical model for the transport of electrons in dense matter are compared to the experimental data. From the comparison it was possible to deduce the population of projectile ion states inside the solid.
