COMPUTER SIMULATION OF COLLISIONALLY EXCITED STATES D.~Loveall, M.B.~Hamley, B.J.~Miller, and K.~Bartschat Department of Physics and Astronomy, Drake University, Des Moines, IA 50311, U.S.A. A Mathematica application for the production of QuickTime movies and GIF animations (angle to time conversion) to represent collisionally excited target states has been developed. The program can be used to visualize the results of electron-impact excitation and ionization processes.
