Abstract
The total thermal inelastic scattering cross section of lead has been measured from transmission of a single crystal, from 2-8 angstroms (0.02-0.0013 ev) at 80°K and 295°K, and is found to be in quantitative agreement with current theory of one-phonon process of energy exchange with the lattice. Measurements of differential cross section at 1.08 angstrom (0.07 ev) are in agreement with Debye-Waller theory. Thus inelastic cross section through the thermal range is found to fit the two theories in their ranges of validity.
