Computer simulations of Na+ scattered on the Ag polycrystalline surface

In this work, the energy distributions of Na ions backscattered on the polycrystalline silver surface are compared to the results obtained in corresponding computer simulations. It is expected relatively low influence of the neutralization effects on the energy distribution in this system, thus the direct comparison of the experimental results with the simulations is reasonable. Well known TRIM code is used as a Monte Carlo simulation and the program SIMKIT as a classical dynamics (CD) algorithm for the simulation of the projectile scattering on different single crystal silver planes. The energy distribution of Na+ ions backscattered on the poly crystalline Ag surface obtained by use of Monte Carlo method is very similar to the corresponding experimental result. However, there is some difference between the distributions in the low energy side. It can be explained by the neutralization effects which can not be neglected in the case of Na+ ions
