Figure 4

Comparison of molecular dynamics computer simulations of 20 keV Ar2000 (top 3 panels) with (CO2)2000 (bottom 3 panels) bombarding a polystyrene substrate at 45º angle of incidence. The time evolution, from 0 ps to 50 ps is noted in the figure. Colors are as follows: argon is yellow, carbon is black, oxygen is red and hydrogen is gray. See text for details about the computation. Note that the evolution of the trajectory proceeds in a very similar fashion for both projectiles, and that no CO2 molecules are observed to fragment in the first 50 ps.
