Wake-Bound-Electron Contribution to Convoy-Electron Velocity Distributions: The Effect of the Ionic Field

In the sudden approximation for surface penetration, a wake-bound electron emerges into vacuum with no net velocity relative to the ion it follows. After exit, the wake electron and ion interact via Coulomb attraction which introduces diffraction structure in the projectile-frame electron velocity distribution. Modeling of the detection process is done in order to compare with experimental results.
