The role of post-collisional, polarisation and exchange effects in energy sharing (e,2e) collisions is considered. Methods of including such effects are assessed. Results are presented for the ionisation of hydrogen and helium gases in coplanar geometry. Results are also presented for the ionisation of helium, argon and xenon in perpendicular plane geometry.
