A theoretical model for studying the heavy particle transport in a cathode sheath is developed.The velocity distribution functions near a planar cathode are deduced.The expressions for neutral and ionic fluxes of neutral and ionic particles near a planar cathode are also obtained.The result predicated by the theoretica l model is in accordance Monte Carlo simulation.
