Zusammenfassung

The excitation spectrum of ripplons at the charged interface of phase-separated 3He-4He mixtures has been determined for electric fields E up to Ec, given by the stability limit of the interface. The frequency ω / 2π of the ripplons is substantially reduced by the presence of the charges, most pronounced for excitations with a wave vector qc equal to the inverse capillary length, where ω→0 when the electric field approaches the critical value Ec. Both Ec and qc depend on temperature via the interfacial properties. In the investigated temperature region, 0.5
