Abstract
We have measured the target thickness dependent convoy electron yieldsY c from hydrogenic Ni27+, Ni28+ (15.6 MeV/u) which is discussed in the framework of an extended model for ELC and ECC in solids considering also contributions from excited states. To understand the target thickness dependent evolution in the case of incident Ni27+ it must be assumed that convoy electrons produced by ELC arise mainly from excited states. The mean transport length λ e for convoy electrons for light projectile ions is equal to the attenuation length of isotachic free electrons λ e , whereas for the heavy ions an enhanced transport length λ e ≫ λ e must be introduced.
