In the experiences carried out on the capacitively excited high‐frequency helium discharges at pressures of 10 −3 −10 −2 Torr, a spectral line intensities redistribution in helium spectrum in function of applied steady magnetic field magnitude has been observed. The magnetic field application modifies also the plasma dispersive properties, which are reflected in the variable relative weight of the h.f. field harmonics. The experiences evidenced an electron temperature dependence on the relative h.f. harmonics intensities, confirming the previous researche conclusion concerning the electron temperature increase with the electric field frequency.
