摘要：
The angular distributions of multiquantum excitations of the lowest energy, frustrated translational vibrations of a low coverage of CO chemisorbed on Cu(001) have been investigated by high resolution helium scattering time-of-flight measurements. The elastic and the one-phonon creation and annihilation cross sections show several interference undulations as a function of parallel momentum transfer, and up to four multiquantum overtones. All the experimental observations are in reasonable agreement with a multiquantum scattering theory, which also provides information on the height and width of the adsorbed CO molecules.
