WebCOMPTON SCATTERING OF X-RAYS FROM NONSPHERICAL CHARGE DISTRIBUTIONS Full Record Related Research Abstract The Waller-Hartree theory for the incoherent Compton scattering of x rays is extended to include the effects, of the inherent nonsphericity of atomic charge distributions. WebJul 28, 2014 · Nonresonant x-ray scattering: we employ a full quantum theory, because inelastic x-ray scattering, also called Compton scattering for short, is a quantum phenomenon [25–27].XFELs provide hard x-rays with photon energy up to about 20 keV, making a nonrelativistic approach sufficient. We utilize nonrelativistic quantum …
WebOn the other hand, the prompt-γ analysis revealed the large reduction of the probability of incoherent scattering due to the 30-fold reduction of the fraction of H, with its exceptionally large incoherent scattering cross section σ H in.sc. = 108 ± 2 b. This effect has led to a major reduction in neutron losses during neutron transport in ...
