Photon interference x-ray absorption fine structure
نویسندگان
چکیده
We report about a fine structure in x-ray absorption spectra, named photon interference x-ray absorption fine structure (pXAFS). pXAFS is due to the interference of x-rays inside the sample and extends across absorption edges. Using a platinum foil pXAFS was measured in a high precision absorption experiment. Excellent agreement with a theoretical pXAFS simulation is achieved in the energy range for above an absorption edge where photoelectron XAFS is negligible. pXAFS provides a method for determination of atomic structure on shortand long-range order scale.

متن کاملRadiative auger effect and extended X-ray emission fine structure (EXEFS).
Radiative Auger spectra are weak X-ray emission spectra near the characteristic X-ray lines. Radiative Auger process is an intrinsic energy-loss process in an atom when a characteristic X-ray photon is emitted, due to an atomic many-body effect. The energy loss spectra correspond to the unoccupied conduction band structure of materials. Therefore the radiative Auger effect is an alternative too...
