The directions of the exiting Au cluster atoms tended to be determined largely by the last collision or two in the channels. Significant numbers of cluster atoms stopped in the target. A example of this is shown in this trajectory plot . The solid lines in the plot represent the path of the cluster atoms, while the green dots show the trajectories of target atoms set in motion by the cluster atoms. The view shown is a projection looking down on the target.
Distances are in Angstroms.
Although this work still is in progress, we expect to submit a paper describing our results in a few months. We have added a Pentium-based computer running both Windows and Linux, that has been optimized to produce computer animations of sputtering events quickly and at low cost. We now are using Rayshade as our basic visualization program. Both Xanim and Imagemagik are used to display animations under UNIX operating systems. A separate DOS program is used to transfer animations to videotape using a low cost video transfer card and a multiformat recorder.
