Figure \ref{fig:force_on_neighbor} shows the radial force exerted on a neighboring Cu atom closest to the projectile (H^+) trajectory as a function of parallel distance to the projectile at different projectile velocities along the [100] channeling trajectory. The forces on the nuclei are evaluated from the time-dependent electron density n(\textbf r, t). The force is obtained by the application of the Hellmann-Feynman theorem\cite{Feynman_1939} theorem\cite{1941}\cite{Feynman_1939}
