Monte Carlo calculations for simulating electron scattering in gas phase

Here we present the derivation, description and results of a Monte Carlo-based algorithm for simulating inelastic scattering of photo-electrons when passing through some scattering medium, such as a gas atmosphere or a solid material. The code used to run these simulations was written in python and is freely available online (https://github.com/surfaceanalytics/montecarlo_electron_scattering).
