This paper gives a complete kinetic theory of atomic discharges
parameters. Very high-frequency discharges and high-pressure continuous
discharges were studied in an earlier paper by the same authors [J.
Plasma Phys. 54, 309 (1995)]; in the
present paper we study low-pressure continuous discharges
or high-frequency discharges whose parameters satisfy different conditions
therefore cannot be described by the earlier model. Analytical results
to a high-frequency argon discharge and to a low-pressure continuous argon
discharge. The results are in good agreement with the numerical results
Ferreira and co-workers.
