Title: Enhancement of the Kapitza conductance at 0.32 meV phonon energy
Issue Date: 1983 Zeitschriftenartikel Journal of low temperature physics 50 (1983), S. 143-150. URL
Abstract: Using quasimonochromatic relaxation phonons emitted by superconducting tunneling functions, the phonon transfer through real solid-liquid helium interfaces was tested. We found an enhancement of the energy transmission if the incident phonons exceed the threshold energy Eo = 0.32 meV. This sharp threshold energy shifts to 0.42 meV if the lighter isotope 3 He is used.
