A linear dependency of the stopping power on the target material is evident in Figure \ref{fig:stopping_power}. It is also observed that if applied density is lower than the experimental value, the stopping power gets lower.   On the other hand if our calculated density remains close to experimental values, the prediction of the stopping powers by TDDFT improves.   Our results show good agreement with Markin \emph{et al.} \cite{Markin_2009} but there are disagreement with those of Cantero \emph{et al.} \cite{Cantero_2009}. We observe $S_\text{e}$ kink around $v \sim 0.1 ~\mathrm{a.u.}$ due to a mixture of d-band $d$-band  in the electronic density of states. For energy loss our new results for $0.01 \leq v \leq 0.06~\mathrm{a.u.}$, are primarily due to s-band $s$-band  electrons. Lack of experimental findings preclude a direct comparison. A model calculation \cite{Correa_private} including the density of states distributions confirm this.% %In the same figure we compare our results with density $6.84~\mathrm{g/cm^3}$ and $8.96~\mathrm{g/cm^3}$.%  %
