\label{fig:log_stopping_power} (color online)  The average $S_\text{e}$ vs. projectile velocity $v$: for a channeling trajectory (red circles)   and for off-channeling trajectory (blue crosses).   The solid black and solid magenta lines refer to the nominal tabulated results from the \textsc{Srim} database for electronic and ionic stopping powers respectively \cite{Ziegler_2010}. Open circles and open squares show data of Cantero \emph{et al.} \cite{Cantero_2009} and Markin \emph{et al.} \cite{Markin_2009} respectively. Dash (green) line and dash-dot (brown) line corresponds to a linear RPA calculation for a free-electron gas with $r_\text{s} = 2.67 ~a_0$ ($1$e per $\mathrm{Cu}$ atom) and $r_\text{s} = 1.12 ~a_0$ ($11$e per $\mathrm{Cu}$ atom). The thin solid black line, obtained by a linear fit to our simulated results, is the polynomial curve $\propto v^q$ to fit the crossover region (with a power of $q = 1.48 \pm 0.02$).  %The optimized density we obtain for the Cu crystal is $8.96~\mathrm{g/cm^3}$ and the available experimental density of Cu was $8.92~\mathrm{g/cm^3}$.% are smaller than the calculated value (of point size).%Proton in Copper Stopping Power: The log-scale of FIG. 2. to show lower projectile velocities $v$ dependence on the structure of copper.  %Results at velocities%
