Among %Among  the measurable quantities associated to the interaction between ions and solids, the stopping power $\mathrm(S)$ \cite{Ferrell_1977} has received much attention; it provides information regarding the energy transfer between the incoming projectile and the solid target in what constitutes a fundamentally non-adiabatic process. %Various models and theories have been proposed to calculate stopping cross sections due to electrons. Employing the First Born Approximation, Bethe \cite{Bethe_1930_EN} has introduced the first calculations of inelastic and ionization cross section. The Bloch correction \cite{Bloch_1933} provides a convenient link between the Bohr and the Bethe scheme.   %Fermi and Teller \cite{Fermi_1947} using electron gas models had reported electronic stopping for various targets.   %The Bethe formula for stopping has been studied in details by Lindhard and Winther \cite{Lindhard_Winther} on the basis of the generalized linear-response theory.
