Deconvolution problems in x-ray absorption fine structure
K. V. Klementev
A Bayesian method application to the deconvolution of EXAFS spectra is considered. It is shown that for purposes of EXAFS spectroscopy, from the infinitely large number of Bayesian…
Possible scenario of the spatially separated Fermi-Bose mixture in the superconductive bismuthates Ba_{1-x}K_xBiO_3
M. Yu. Kagan, A. P. Menushenkov, K. V. Klementev +1
A new scenario for superconductivity in the bismuthates based on the concept of a spatially separated Fermi-Bose mixture is proposed. In the framework of this scenario we qualitati…
XAFS spectroscopy. II. Statistical evaluations in the fitting problems
K. V. Klementev
The problem of error analysis is addressed in stages beginning with the case of uncorrelated parameters and proceeding to the Bayesian problem that takes into account all possible…
XAFS spectroscopy. I. Extracting the fine structure from the absorption spectra
K. V. Klementev
Three independent techniques are used to separate fine structure from the absorption spectra, the background function in which is approximated by (i) smoothing spline. We propose a…
EXAFS indication of double-well potential for oxygen vibration in Ba_{1-x}K_xBiO_3
A. P. Menushenkov, K. V. Klementev
X-ray absorption spectra of oxide systems Ba_{1-x}K_xBiO_3 and BaPbO_3 above Bi- and Pb-L3 absorption edges were investigated. It was shown that oxygen ions move in double-well pot…
