At low velocity, our results show good agreement with Markin those of  \emph{et al.} \cite{Markin_2009} but a relative disagreement with those 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}.  Below $0.02~\mathrm{a.u.}$, the lack of experimental points preclude 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 at $v > 0.02~\mathrm{a.u.}$.
