A NEW EVALUATION FOR X-RAY ABSORPTION SPECTRA IN THE KANES REGION

A wavelet analysis for X-ray absorption spectra

X-ray absorption spectroscopy (XAS) is a powerful tool for the investigation of molecules in solution, but the complex origin of these spectra means that theoretical simulations are critical. Presently, calculations are most reliable when the photoelectron is not sensitive to the fine details of the atomic potential, i.e., in the EXAFS region which is the most attractive for local structural an...

A method for normalization of X-ray absorption spectra.

Accurate normalization of X-ray absorption data is essential for quantitative analysis of near-edge features. A method, implemented as the program MBACK, to normalize X-ray absorption data to tabulated mass absorption coefficients is described. Comparison of conventional normalization methods with MBACK demonstrates that the new normalization method is not sensitive to the shape of the backgrou...

Beyond the Pair Distribution Function in X-ray Absorption Spectra

Evaluation of X-Ray Absorption by Ointment Containing Bismuth Oxide Nanoparticles in Radiology Staff

Introduction: The effects of X-rays on carcinogens have been proven in recent years. Today, lead is used in many devices such as lead covers, thyroid protectors to protect the body against x-rays. But this equipment contains many disadvantages such as, Toxicity, High weight and Lack of flexibility. Today, newer methods, such as semi-solid skin care products (cream, ointment), a...

Multielectron Excitations in X-Ray Absorption Spectra of KOH

The X-ray absorption spectra have been measured near Kedge of a crystalline KOH. After the subtraction of XAFS oscillation, several features caused by multielectron transitions suggested on noble gases were detected on K in solid phase and analyzed by the use of the shakeup and shakeoff probabilities. The [ls2p], [ls3s], and [ls3p] transition onsets have been identified in the compound.
