There are seven animations linked on this page. Five animations are from the work of Zbigniew Postawa and shows the effect of C60 bombardment of Ag. Two are from Arnaud Delcorte's work of Ar sputtering of polystyrene on Ag. They exhibit high and low action events. Enjoy!

The two trajectories presented below exhibit the diversity of sputtering events. These trajectories come from the work of Arnaud Delcorte (Ref 198 and 206 below) of sputtering of polystyrene tetramers on a metal surface. Below is Figure 2 of Ref 206. The trajectories have been categorized according to ejection yield of molecules and action in the Ag substrate.

The staff at the Faculty Multimedia Center at Penn State have converted our sputtering animations to streaming video that can be viewed on a PC or MAC (sorry no UNIX) with Quicktime. Each animation has been subdivided into segments. Each segment has been made into a high resolution copy appropriate for LAN access. In addition, there is a copy of each segment for DOWNLOAD that also can be used with Quicktime.
During the summer of 1992, Roger Webb from the University of Surrey, UK, and Roger Smith from Loughborough University, UK, visited Penn State for two weeks. Along with Eric Dawnkaski they made SPUT92. We published the animation along with an extensive text in the International Video J. of Engineering Research (John Wiley & Sons, Ltd) 3, 63-72 (1993).

Experimental energy and angular distributions of neutral Rh atoms sputtered in the excited 4F7/2 state vs. the ground 4F9/2 state indicate anomolous excitations probabilities for the low energy excited 4F7/2 Rh atoms. Simulations clearly show that collisions of atoms above the surface are responsible for the anomolous excitation probability. The original animation was made by Dan N. Bernardo. The color coding for the atoms is shown to the left. See the references given below for further details.
