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).
