“…Nevertheless, our results indicate that the Au5p 3/2 electron energy loss can successfully be used in the Extended Energy Loss Fine Structure method for determination of nearest neighbor distance of gold atoms in the solid state surface layer. This thesis can be supported by the circumstance that the difference 0.15Å mentioned above is not greater than such difference found for shallow levels of copper and nickel in [5][6][7][8].…”

“…As a result, information obtained with the use of EELFS concerns the surface layer of the sample investigated while information given by EXAFS is rather connected with the bulk. For this reason, shallow core levels (M 2,3 levels of 3d transition metals) were tested with an appreciable success by a number of authors [5][6][7][8][9][10][11]. In [5][6][7][8] differences between distances to the first neighbors measured and these taken from the crystallographic data were in the range of 0.2Å for Cu, Ni or Fe but Guy et al [11] obtained these differences between 0.01 and 0.04Å using more sophisticated mathematical elaboration of experimental results.…”

“…22 The total phase-shift, which contains contributions from both processes, leads to displacement of the RDF peaks of typically 0.2-0.3 Å from their true values in EXELFS (and EXAFS) analyses. 26,31,32 This total phase-shift depends on the k-range selected for FT and also on the edge type above which the oscillations were selected for the EXELFS analysis. 22 Since a reasonable krange was selected in the present study, and it is known that the experimentally calculated nearest-neighbor distance in the EXELFS analysis differs from the known first nearestneighbor distances reported above by 0.3 6 0.02 Å , a total phase-shift of 0.3 Å was added to the experimental RDF.…”

Appl. Phys. 110, 043515 (2011); 10.1063/1.3624735Melting and supercooling studies in submicron Al particles using valence electron energy-loss spectroscopy in a transmission electron microscope Extended energy-loss fine structure (EXELFS) analysis was used to study the behavior of the nearest-neighbor atomic distance and thermal vibration behavior of pure Al particles heated and cooled through the melting temperature in situ in a transmission electron microscope. The results show that the increase in first nearest-neighbor distance for solid Al with temperature compares reasonably well with calculated values based on thermal expansion and that anharmonic thermal vibrations lead to an asymmetry in the Gaussian shape of radial-distribution function (RDF) peaks with temperature. In addition to thermal disorder, structural disorder also contributes to an increased asymmetry in the RDF peaks in liquid Al. Comparison of the first nearest-neighbor distance change with the inverse volume plasmon energy obtained from a previous study shows that the nearest-neighbor distance does not follow the same hysteresis as the plasmon energy during supercooling of liquid Al. The apparent contraction in the nearest-neighbor distance observed during supercooling is explained as due to the asymmetry in the RDF peaks at high temperatures caused by the thermal vibrations, possibly combined with the formation of local (icosahedral) clusters in the liquid.
