\label{fig:force_on_proton} (color online). Proton in Copper: Force on proton moving with $v = 1.8 ~\mathrm{a.u.}$ in (x,y,z) directions as a function of its position with respect to the center of the cluster. Where red, black and blue lines denotes x, y and z directions respectively along the [100] channeling trajectory. The solid darkgreen horizontal line represents Note that the force in  the negative direction  of the velocity (solid green) does not average to zero, the average (negative) value agrees with the  stopping power at $v = 1.8 ~\mathrm{a.u.}$. calculated from the energy increase (Fig.~).  Note that there is transient effect at first, then the projectile reenters in the periodic supercell at $x = 20.46573246 20.46  a_0$.
