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. WebThe total photoabsorbtion cross section oY (ET) for stable nuclides has been thoroughly investigated up to EY energies ranging from 25 to 30 MeV, as well as the basic components of the total cross section in this energy range, namely, the (y,n) and (y,2n) reactions. For other isotopes data exists for the (y,3n) reactions in the vicinity of the ...

WebSep 1, 1991 · We have performed molecular orbital calculations for SF6 and H2S, using the discrete–variational Xα method. Energies and cross sections of virtual states are obtained for theoretical spectra of sulfur K, LII,III and fluorine K x‐ray absorptions for the SF6 molecule. They are in good agreement with the experimental results.

Two-photon absorption (TPA or 2PA) or two-photon excitation or non-linear absorption is the simultaneous absorption of two photons of identical or different frequencies in order to excite a molecule from one state (usually the ground state) to a higher energy, most commonly an excited electronic state. Absorption of two photons with different frequencies is called non-degenerate …
