The r-f spectrum of a gaseous discharge in a strong magnetic field is measured with the aid of a fixed frequency receiver by sweeping the magnetic field by approximately two percent. Source of radiation and receiving equipment are described. The following results were obtained a series of emission lines around the cyclotron frequency, an emission at a frequency which increases with increasing magnetic field strength and decreases with increasing external voltage, and a strong resonance when both frequencies coincide. The intensity increases by a factor of 100 and more. The frequency spectrum is discussed in terms of a simple theory, which accounts for local space-charge fields. Their spatial distribution is inferred from the frequency behavior of the emission lines. Finally, a mechanism is suggested that classifies the resonance effect as an energy transfer from a longitudinal plasma mode into electromagnetic radiation. (auth)
