Many-pole model of inelastic losses in x-ray absorption spectra
J. J. Kas, A. P. Sorini, M. P. Prange +3
Inelastic losses are crucial to a quantitative analysis of x-ray absorption spectra. However, current treatments are semi-phenomenological in nature. Here a first-principles, many-…
Deconvolving Instrumental and Intrinsic Broadening in Excited State X-ray Spectroscopies
T. T. Fister, G. T. Seidler, J. J. Rehr +4
Intrinsic and experimental mechanisms frequently lead to broadening of spectral features in excited-state spectroscopies. For example, intrinsic broadening occurs in x-ray absorpti…
Ab initio calculations of mean free paths and stopping powers
A. P. Sorini, J. J. Kas, J. J. Rehr +2
A method is presented for first-principles calculations of inelastic mean free paths and stopping powers in condensed matter over a broad energy range. The method is based on {\it…
Ab initio calculations of inelastic losses and optical constants
J. J. Rehr, J. J. Kas, M. P. Prange +4
Ab initio approaches are introduced for calculations of inelastic losses and vibrational damping in core level x-ray and electron spectroscopies. From the dielectric response funct…
