Résumé:
We compare the results obtained in the
study of a weakly ionized gas for a Townsend discharge
which is developped in a steady uniform
field. This study has been carried out in two laboratories
: firstly at the Centre de Physique Atomique
de Toulouse using Boltzmann equation (1) and
secondly in Paris (Ecole Supe'rieure dl~lectricitk)
by Monte Carlo simulation.
