Wee k 2: Concept of a Distribution Function, Forms of the Distribution Function
Momentum transfer between the light electrons and the heavier gas molecules and plasma ions is not very efficient and often the energy deposition into the plasma favours the electrons. As a result ionized gases are described as non-thermal or non-equilibrium, i.e. the constituent e.g. electrons, ions, and gas molecules are each in thermal equilibrium with similar mass species, but not with different mass species.The velocity distribution of each species can often be represented by a Maxwell-Boltzmann distribution and the energy distribution quantified by a temperature.
