Spectrum of electrons localized above liquid 3He
Volodin A.P., Edel'man V.S.
The spectrum of electrons localized above 3He was measured. The difference between the natural frequencies and those given by the hydrogen-like model, as in 4He, is shown to be small and does not exceed 3~A%. The similarity between the spectra of electrons above 3He and those above 4He indicates that the structure of the liquid-vapor interface is identical.
