Abstract

Spectra excited in hollow cathode discharges operating at high frequency (27.2 MHz) and direct currents have been compared. The cathodes made of copper, brass and steel and argon as a carrier gas were used. Line intensity ratios (I_hf/I_dc) for species excited at different pressures have been investigated and discussed.
