Abstract
Energy-transfer events have been observed between a He atom and a Cu(001) surface at 16°K. Only phonon creation events were observed which were confined to the subspecular region. Parallel momentum was conserved and bulk and surface modes detected. For an ordered Xe layer, both phonon creation and annihilation events were detected and parallel momentum was not conserved.Keywords
