Fig. thFig.  \ref{fig:stopping_power} shows a comparison of our calculated $S_\text{e}$ with \textsc{Srim} experimental data and model. In the \emph{channeling} case, the maximum of stopping is lower in value and velocity compared to the \textsc{Srim} database and the \emph{off-channeling}, after the maximum it decreases faster.  For the off-channeling case, there is a better agreement between our $S_\text{e}$ results with the \textsc{Srim} data in most of the range.  

At low velocity it is observed that the off-channeling and channeling simulated results collapse into a common curve,   this effect has been seen in the simulations before \cite{Correa_2012,Schleife_2015,Ullah_2015}.   The effect is that the computed quantity  less sensitive to the precise geometry of the trajectory, as the geometric cross section increases. We speculate that this is because the effective binary cross section increases making the energy loss less sensitive to the impact parameters averaging prescription. %We also see that at low velocity the off-channeling and channeling simulated results collapse into a common curve,   %this effect has been seen in the simulations before \cite{Correa_2012,Schleife_2015,Ullah_2015},   %at low velocity the effect is less sensitive to the precise geometry of the trajectory,
