Essential Questions and Answers on X-ray absorption in "SCIENCE»PHYSICS"
What is X-ray absorption?
What do XAS studies measure?
XAS studies measure electron density distributions and energy levels, as well as other parameters such as excitation energy or chemical environment.
What is required for an XAS experiment?
An XAS experiment requires a sample, an intense beam of monochromatic x-rays, a detector, and data acquisition/analysis software.
What type of information can be obtained from an XAS experiment?
An XAS experiment can provide information about elemental compositions, chemical bonding states, oxidation states, structural features and short range ordering.
Does an XAS experiment require sample preparation?
Generally yes; most samples must be finely ground or purified before they are ready to be tested. However some samples can be tested directly without any additional preparation.
Final Words:
Through the use of intense beams of monochromatic x-rays to interact with certain materials, detailed information about electron density distributions and energy levels among other parameters can be revealed by means of an X-ray absorption (XAS) study.
