Photoabsorbtion
WebFeb 14, 2024 · The dynamics of photoabsorption, photoionization, and the associated Auger decay have been investigated at the carbon K edge in methyl iodide (CH3I) using linearly polarized synchrotron radiation. Ion yield measurements were used to investigate transitions in the pre-edge region due to excitations into either unoccupied valence or Rydberg states. Photoionization is the physical process in which an ion is formed from the interaction of a photon with an atom or molecule.

WebPhotoabsorption Photon absorption by an atomic electron occurs in the photoelectric effect process, in which the photon loses its entire energy to an atomic electron which is in turn liberated from the atom. WebThe XCOM program can generate cross sections on a standard energy grid (spaced approximately logarithmically), or on a grid selected by the user, or for a mix of both grids. …

WebJul 18, 2014 · The x-ray pulse (purple) arrives after a certain time delay and creates one or a few inner-shell vacancies through absorption of single or multiple photons by the iodine M shell. This is followed by a fast local Auger decay that creates additional charge.
