Abstract
We studied the scattering of low-energetic neutral hydrogen atoms from the surface of liquid helium by a capillary flow method at sub-Kelvin temperatures. With decreasing temperature a decreasing flow impedance is observed, which may be interpreted as arising from an increasing probability of elastic surface scattering. This behavior is compared with a model for atom-surface scattering. Emphasis is put on the quantum nature of the scattering process.
