XAFS conference proceedings and JSR.
This issue brings together papers from the 10th International Conference on X-ray Absorption Fine Structure (XAFS X) held in Chicago in August 1998. This is one of the major synchrotron radiation conferences, held every two years since 1981 when the ®rst international meeting of XAFS experts was held in Daresbury, coincident with the operation of the ®rst of the second-generation dedicated sync...
متن کاملElements of XAFS
Introduction Over the last two decades X-ray Absorption Fine Structure (XAFS) spectroscopy has emerged as an incisive probe of the local structure around selected atomic species in solids, liquids, and molecular gases. Foremost among its strengths are its applicability to amorphous materials and its \tunability" { the ability to probe the environments of di erent elements in the sample by selec...
متن کاملAutomatic XAFS measurement system developed at BL14B2 in SPring-8
A novel XAFS measurement system has been developed in which XAFS measurements can be performed including sample-loading and detector adjustments. With this system, XAFS measurements of up to 80 samples in both transmission and fluorescence modes can be carried out. The adjustment of the optical components has also been automated. It not only saves manpower and measurement time, but also improve...
متن کاملXAFS Data Interchange: A single spectrum XAFS data file format
We propose a standard data format for the interchange of XAFS data. The XAFS Data Interchange (XDI) standard is meant to encapsulate a single spectrum of XAFS along with relevant metadata. XDI is a text-based format with a simple syntax which clearly delineates metadata from the data table in a way that is easily interpreted both by a computer and by a human. The metadata header is inspired by ...
متن کاملXAFS studies of nickel-doped lead telluride
The problem of impurities and defect states in lead telluride-based semiconductors is of crucial importance for their practical applications. X-ray absorption fine structure (XAFS) techniques are capable to address some of the key issues regarding impurities position, their valent state, as well as the local structural changes of the host lattice in the immediate surrounding of the impurity ato...
