Theoretical and experimental determinations of the electron energy distribution for a positive-column plasma have been used with the published data for other heavy inert gases to show that at pressures $p\le 1$ Torr and low discharge currents, a substantial part is played in producing the low-energy part of the energy distributions in this xenon or other heavy inert-gas plasma by inelastic collisions between electrons and atoms, which leads to a Druvestein distribution for this energy range.
