The average stopping power ($S_\text{e}$) 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 squares are previous data of Markin \emph{et al.} \cite{Markin_2009}. Dash (green) line and dash-dot (brown) line corresponds to a linear RPA calculation for a free-electron gas with $r_\text{s} = 2.67 ~\mathrm{a.u.}$ (1 electron per $\mathrm{Cu}$ atom) and $r_\text{s} = 1.12 ~\mathrm{a.u.}$ (11 electron per $\mathrm{Cu}$ atom).   The thin solid black line is the polynomial curve $\proto $\propto  v^n$ to fit the crossover region (with a power of $n = 1.455$). %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%  %The gray dots refers to the SRIM experimental database\cite{Ziegler_2010}.%
