For this purpose, they have to be coupled with a Monte Carlo Collisional module able to model charged particle interaction with a background gas via random numbers. Argon is deeply used as background gas in such simulations, but numerical data or interpolation formula of electron and ion impact cross section are not so easy to collect. In this short report, interpolating formulae and energy range of validity will be presented, as extracted from XOOPIC sources. The Author M. Frignani, G. Grasso The Supervisor prof.
