On temperature broadening in X-ray spectra of metals

Hedin, Lars LU and Rosengren, Anders (1977) In Journal of Physics F: Metal Physics 7(7). p.1339-1348
Abstract
Calculates the full width at half maximum (FWHM) of the phonon broadening function for Li, Na, K and Al at different temperatures. A theory is used which employs the ionic pseudopotential, rather than, as in Bergersen et al's (1971) theory, a bare Coulomb potential. Despite the fact that a pseudopotential in a general sense is weaker than a Coulomb potential the authors find that the former gives considerably larger FWHM's, e.g. in Li at T=0 the FWHM becomes more that doubled. They also discuss other broadening effects and conclude that their results are consistent with recent experimental data presented by Baer et al. (1976).
