Surface extended X-ray absorption fine structure is the surface sensitive equivalent of the EXAFS technique.

X-ray absorption edge spectroscopy corresponds to the transition from a core-level to an unoccupied orbital or band and mainly reflects the electronic unoccupied states.

X-ray absorptions are associated with the excitation of inner shell electrons in atoms.

The hollow atom becomes transparent to X-ray absorption, but still scatters X-rays.

Philips thought about the nerve-cell death he'd seen in Pathology, but clearly that wasn't enough to affect X-ray absorption.

His calculations accorded with observations of the X-ray absorption of the sun, but not hydrogen.

The accelerated rate was due to the secondary electron exposure, while the gradual rate was due to the X-ray absorption.

The phenomenon is called extended X-ray absorption fine structure, or EXAFS for short, and is quite general to condensed matter.

X-ray absorption is reported as which orbital absorped the x-ray photon.
