%  %It is an attractive method because it is both self-consistency and non-perturbative \cite{Kohn_1965} allowing for an atomistic \emph{ab initio} description at a reasonable computational cost for simulation cells below a few hundred atoms. Alternatively, time dependent tight-binding have been proposed as well to overcome some size limitations \cite{Mason_2012} at the price of additional approximations.  In studying the role of ion-solid interactions in $\mathrm{H^+ + Al}$, Correa \emph{et al.} \cite{Correa_2012} have shown that the electronic excitations affect affects  the interatomic forces relative to the adiabatic outcome. Recently, Recently  Schleife \emph{et al.} \cite{Schleife_2015} have calculated the electronic stopping power ($S_\text{e}$) by $\mathrm{H^+}$ $\mathrm{H}$  and $\mathrm{He^{+2}}$ $\mathrm{He}$  projectile including TDDFT non-adiabatic electron dynamics and found that off-channeling trajectories along with the inclusion of semicore electrons enhance $S_\text{e}$ $S_\text{e}$,  resulting in better agreement with the \textsc{Srim} data \cite{Ziegler_2010}. \textsc{Srim} \cite{Ziegler_2010} also provides both awidely used  fitted model for electronic stopping as well as a large set of experimental points. In this Letter case  we concentrate in a metal with a richer electronic band structure around the Fermi energy, such as $\mathrm{Cu}$. %
