abstract = {Extended X-ray absorption fine structure (EXAFS) spectra
are sensitive to thermal disorder and are often used to
probe local lattice dynamics. Variations in interatomic
distances induced by atomic vibrations are described by the
temperature-dependent mean-square relative displacement
(MSRD), also known as the Debye-Waller factor. In this
study, we evaluated the feasibility of addressing the
inverse problem, i.e., determining the sample temperature
from the analysis of its EXAFS spectrum using the
multiple-scattering formalism, considering contributions up
to the 4th-7th coordination shell. The method was tested on
several monatomic metals (bcc Cr, Mo, and W; fcc Cu and Ag),
where the correlated Debye model of lattice dynamics
provides a fairly accurate description of thermal disorder
effects up to distant coordination shells. We found that the
accuracy of the method strongly depends on the temperature
range. The method fails at low temperatures, where quantum
effects dominate and MSRD values change only slightly.
However, it becomes more accurate at higher temperatures,
where the MSRD shows a near-linear dependence on
temperature.},
