Enhanced helium-atom scattering from longitudinal surface phonons in Cu(001)
- 1. Max-Planck-Institut fuer Stroemungsforschung, Bunsenstrasse 10, D-3400 Goettingen (Germany)
Description
Inelastic helium-atom scattering from Cu(001) shows giant intensities for the longitudinal-surface-phonon resonance. This effect, most pronounced in the left-angle 100 right-angle direction and not visible with electron-energy-loss spectroscopy, indicates a very large anisotropic deformability of conduction electrons against the longitudinal modes of surface atoms. Its size and anisotropy are well accounted for by a pseudocharge model for surface dynamics
