Modelling results obtained with PLASIMO using the 4-species RKM (reaction kinetic model). The data contains period-averaged density and mean energy of electrons as well as the density of heavy-particle species in stationary state of the RF glow discharges in argon. Modelling was carried out using a sinusoidal voltage with an amplitude of 350 V and a frequency of 13.56 MHz . A gap distance of 1 cm, a gas pressure of 1 Torr and a gas temperature of 300 K were also considered for the modelling.
