XASLIB: The X-ray Absorption Data Library

This is a collection of experimentally measured X-ray Absorption Spectra.

The data here represent the enegy-depenent X-ray absorption coefficient, \(\mu(E)\), around X-ray aborption edges on a range of elements and materials as used for X-ray absorption spectroscopy (XAS, XAFS, or XANES). Using the conventions of the XAS community, the energies here are recorded in electron-Volts (\(eV\)) and values for absorption are left “un-normalized” - not necessarily scaled to any particular units. Most of the data will has been measured in Transmission mode, though some has been measured in Fluorescence or other Emission modes.

See Measurement Modes for definitions.
