Abstract

We test the conjecture that convoy electrons emitted from solid targets originate from electrons bound in the potential wake trailing the traversing ion. Although we observe distinct differences in the longitudinal velocity distribution between solid and gaseous targets, we do not observe the predicted ${Z}_{1}$, velocity, and target-material dependences. From this we conclude that the majority of convoy electrons from solids do not originate from wake-bound electrons.
