Classification: 2.4, 4.14.

Nature of problem:
A general Mathematica application is presented that allows for the production of individual frames as well as movies (angle to time conversion) to visualize the charge cloud distribution of collisionally excited states [1-3].

Solution method:
Input data representing complex scattering amplitudes are converted into general formulas that describe the charge cloud of interest. Individual frames are produced and exported into a frame-to-movie converter.

Restrictions:
Limitations are set by the available RAM and disk memory.

Running time:
The test run performed to compute eleven picture frames took 26 seconds on a PowerMacintosh G3/266. In addition, it took approximately four minutes to output the EPS files on this machine.
