Debye-Waller factor for elemental crystals
Abstract
A simple model for the Debye-Waller factor is proposed which is based on the familiar high- and low-temperature expansions and allows one to determine this quantity at an arbitrary temperature with a typical accuracy of 2 to 3%. The coefficients in the model are determined from phonon density-of-states curves obtained from neutron inelastic scattering measurements and are tabulated for 43 elements with the f.c.c., b.c.c., h.c.p. and diamond structures.
