At low velocity, our results show good agreement with the experiments of Markin \emph{et al.} \cite{Markin_2009} but a relative disagreement with the findings of Cantero \emph{et al.} \cite{Cantero_2009} and the \textsc{Srim} model.   This could be a simple experimental scaling issue related to the difference between measuring relative and absolute stopping power at low velocities \cite{Markin_2009}.  We expect similar results for other  transition metals\cite{Markin_2008}. metals, as described by Ref.~\cite{Markin_2008}.  Below $0.02~\mathrm{a.u.}$, the lack of experimental points precludes a direct comparison, but we find a large deviation from linear behavior.   One possible explanation is that bound effects break down the linear response (Linhard) approximation that was useful to interpret the different regimes (and crossover) for velocities above $0.02~\mathrm{a.u.}$.
