Nonlinear cyclotron resonance of electrons localized over the surface of liquid helium
Edel'man V.S.
An investigation of cyclotron resonance of electrons localized over the surface of liquid helium, at 7Ъ^0.4 К, has revealed heating of electrons by radiation of frequency ~ 17.8 GHz and a power ~10-10 W, causing them to go over from the ground state into the quasicontinuum. A narrow resonance line appeared, and its relative width reached ~ 2XlO~5 in a field that corresponds to cyclotron resonance of the free electrons, and is independent of the angle between the magnetic field and the normal to the surface of the liquid.
