Abstract

On atomically clean surfaces, the anomalous Kapitza transmission is absent, but it can be restored by minute amounts of adatoms [1]. The adatoms supposedly form localized excitations (“two level systems”) which absorb and emit phonons by direct coupling to the solid and to the helium [2]. The same mechanism may also work on ordinary, or “real” surfaces which have been held on air, or treated with organic solvents. A specific experiment for these ordinary surfaces was missing so far. In fact, the Kapitza transmission was generally found to be unspecific, and did not depend much on phonon polarization [3,4], frequency [5,6], angle of incidence [7], or on surface treatment [8].
