Role of quantum nuclei and local fields in the x-ray absorption spectra of water and ice
Role of quantum nuclei local fields the x-ray absorption spectra of water and ice Chemical Physics
2012/4/19
We calculate the x-ray absorption spectra of liquid water at ambient conditions and of hexagonal ice close to melting, using a static GW approach that includes approximately local field effects. Quant...
Quantitative Estimation Methods for Concentrations and Layer Thicknesses of Elements Using Edge-jump Ratios of X-ray Absorption Spectra
Quantitative Estimation Methods Concentrations Layer Thicknesses Elements Using Edge-jump Ratios of X-ray Absorption Spectra
2010/9/17
This work concerns the development of quantitative estimation techniques using the K edge-jump ratio of X-ray absorption spectrum recorded through total-electron-yield measurements. The three methods ...
Determination of the host phase of rare earth elements in natural carbonate using X-ray absorption near-edge structure
