%In the low energy region the energy loss in metal is due to the excitation of a portion of electrons around the Fermi level to empty states in the conducting band at higher energies, a minimum momentum transfer due to the limited response time of target electrons to the projectile ions. In this paper we concentrate in the near and below the maximum of stopping down to the low velocity regime for $\mathrm{H}$ in $\mathrm{Cu}$.  %  %A unified \emph{ab initio} theoretical approach suitable for different projectiles and energies is in its developing stages \cite{Pruneda_2007,Schleife_2015,Ullah_2015}. For calculating electronic stopping and radiation damage in metals there are few reviews (for example, Ref.~\cite{Race_2010} and references therein).  Using a quantal method based on TDDFT, Quijada {\emph et al} \cite{Quijada_2007} have studied the energy loss of protons and anti-protons moving inside metallic $\mathrm{Al}$ and obtained good results for the projectile-target energy transfer over a wider energy range.   Recently Uddin {\emph et al.} \cite{Alfaz_Uddin_2013} and Haque {\emph et al.} have calculated stopping cross sections for various media with atomic number $Z=2$ to $100$ using realistic electron density with fitted parameters and obtained close agreement with the experimental and \textsc{Srim} data.
