The motion of electrons in sulfur hexafluoride in uniform electric fields is simulated using a Monte Carlo method. The evaluated swarm parameters are compared with experimental results for drift velocity, electron mean energy, ratio of ionization coefficient and attachment coefficient. The electron - molecule collision cross sections adopted in the simulation result are in a good agreement with the experimental values over the range of E/N investigated (E is the electric field and N is the gas number density of background gas molecules).
