Simulation of ion-molecule collisions in inhomogeneous time-depended electrogasdynamic fields

Computer based procedures have been developed and tested to simulate the ion motion in inhomogeneous time-depended electrogasdynamic fields. Procedures are based on combined model of ion-molecule collision. This combined approach takes into account both repulsive and attractive region of the interaction potential and correctly describes the ion scattering over a wide range of collision energies. Models and computational procedures developed enable to introduce the anisotropic modes of scattering. Monte Carlo simulation of free path length ore free time is based on time discretization technique, which is well combined with discretization of motion equations.
