Fig. 4
Snapshot of the event shown in Fig. 3 at 11 ps after particle impact. At this time also sideways and forward sputtering have set in. In this presentation, thanks to transparency (blue particles), the recoil particles inside the sphere are also seen. Only the particles with a kinetic energy above 0.4 eV are displayed. Particles with kinetic energy between 0.4 and 1 eV are colored from green to light red, particles above 1 eV in dark red
