Microwave resonance in germanium was registered by means of the change of the intensity of the luminescence of electron-hole drops (EHD). A resonant decrease of the luminescence of the EHD was observed at the cyclotron-resonance frequencies of the free carriers. At large microwave powers, an intense line that did not agree with the cyclotron-resonance spectrum was observed.
