Layer-Dependent Surface Mean-Square Vibration Amplitudes by Low-Energy-Electron Diffraction

The surface-vibration properties of solid xenon are investigated by low-energy-electron diffraction. Using no adjustable parameters, calculated layer-dependent mean-square vibration amplitudes and scattering factors of solid xenon are used to determine the surface Debye temperature of the xenon (111) face. The magnitude of inelastic electron damping as a function of incident electron energy in solid xenon is also determined. Results of the calculation are compared with experimental measurements for a range of energies from 0 to 400 eV.
