\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. traveled distance.  Where red, black and blue lines denotes x, y $x$, $y$  and z $z$  directions respectively along the [100] channeling trajectory. Note that the force in the direction of the velocity (solid green) does not average to zero, the average (negative) value agrees with the stopping power calculated from the energy increase (Fig.~). Note that there is transient effect at first, first ($\lesssim 5~a_0$),  then the projectile reenters in the periodic supercell at $x = 20.46 a_0$. $\gtr 20.46~a_0$.
