Although experimental values have considerable vertical spread,   our calculated stopping power is on the low side for  most of the points and also below the fitted by \textsc{Srim} model \cite{Ziegler_2010}. While this could be partially  explained by taking into account  off-channeling trajectories near the peak, (off-channeling has been reported to increase the electronic stopping power by approximately a factor of two for several materials \cite{Dorado_1993}, \cite{Schleife_2015}),   at low velocities a different explanation must be sought.  On this lines we would like to note that more sophisticated approaches,  based on the dielectric and current current-density  response but including the exact many-body and dynamic exchange-correlation  treatment, are available in the literature \cite{Nazarov_2007}.   These types approaches which are beyond the current scope of this work,  may contain explicitly  additional channels of dissipation not taken into account in our adiabatic exchange and correlation functionals that can be relatively important at low velocities.
