Abstract Experimental results on some properties of electric discharge initiated by audio frequency voltages in the range of 50–10000 Hz are presented. These results indicate that there are at least two modes of plasma ionic oscillations. A resonance-type behavior is seen when the driving field frequency becomes equal to the plasma ionic frequency. The results for plasma density and plasma temperature for both modes are presented.
