Recently, from a phenomenological point of view, Uddin \emph{et al.} \cite{Alfaz_Uddin_2013} have calculated $S_\text{e}$ for protons, $\alpha$ and $\mathrm{He}$ for various media with atomic number $Z=2$ to $100$ using realistic electron density with four fitted parameters and obtained $\sim 15\%$ agreement with the \textsc{Srim} data \cite{Ziegler_2010}. Using a single formula with fewer parameters Haque {\emph et \emph{et  al.} \cite{Haque_2015} have reported proton stopping power with encouraging results. The development of time dependent density functional theory (TDDFT) \cite{Runge_1984} enhanced the study of many body problems and in particular the problem at hand.   It has enjoyed much consideration owing to its electron dynamics both self-consistency and non-perturbative way \cite{Kohn_1965} and allowed for an atomistic \emph{ab initio} perspective.
