Although experimental values have considerable vertical spread,
our calculated stopping power is on the low side most of the points and also below the fitted by \textsc{Srim} model \cite{Ziegler_2010}.
While this could be explained by taking 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 response but including
the exact many-body and dynamic exchange-correlation
treatment, are available in the literature \cite{Nazarov_2007}.
These types approaches may contain additional channels of dissipation not taken into account in our adiabatic exchange and correlation functionals that can be relatively important at low velocities.
