We disentangled channeling and off-channeling effects and observe a collapse of the two curves at low velocities; and identified five regimes  i) the linear $\mathrm{s}$-only ($0.02-0.07~\mathrm{a.u.}$),   ii) linear $\mathrm{s}+\mathrm{d}$ ($0.3-1~\mathrm{a.u.}$),   iii) crossover with $\sim 1.5$-power law ($0.07-0.3~\mathrm{a.u.}$) and iv) plasmon-like ($v > 1~\mathrm{a.u.}$) 1~\mathrm{a.u.}$).  %and v) what is possibly a non-linear screening regime at $v < 0.02~\mathrm{a.u.}$. This is a further illustration that the electronic stopping in general does not posses a simple behavior in the limit $v\to 0$, and that band and bound effects dominate this behavior.
