Using a Kohn-Sham (KS) scheme of time-dependent density functional theory (TDDFT) where the KS wave functions are expanded in a basis set of spherical harmonics, Quijada {\emph et al} \cite{Quijada_2007} have studied the energy loss of protons and anti-protons moving inside metallic $\mathrm{Al}$ (spherical Jellium) clusters and obtained good results for the projectile-target energy transfer over a restricted energy range.   Recently Uddin \emph{et al.} \cite{Alfaz_Uddin_2013} and Haque \emph{et al.} \cite{Haque_2015} have calculated stopping cross sections for various media using atomic density functions from Dirac-Hartree-Fock-Slater wave functions in the Lindhard-Schraff theory \cite{Lindhard_Scharff} with fitted parameters and obtained close agreement with the experimental and \textsc{Srim} data.  \textsc{Srim} \cite{Ziegler_2010} provides both a fitted model for electronic stopping as well as a large set of experimental points.
