Title: Extended x-ray absorption fine structure Debye-Waller factors. I. Monatomic crystals
Abstract: Debye-Waller factors in the extended x-ray absorption fine structure (EXAFS) are related to the mean-square fluctuations in interatomic distances, ${\ensuremath{\sigma}}_{R}^{2}$. Monte Carlo calculations of ${\ensuremath{\sigma}}_{R}^{2}$ based on lattice-dynamical models are presented for crystalline Cu, Fe, and Pt. The results are compared with correlated Einstein and Debye models, with experimental data and with the mean-square vibrational amplitudes ${{u}_{\stackrel{^}{q}}}^{2}$ which enter the Debye-Waller factor in x-ray diffraction.
