WebMay 8, 2007 · 7 provides an intuitive means for comparing the efficiencies of coherent vs. incoherent processes. Its physical interpretation is very clear: at maximal coherence (ρ bc = 1/2) the ratio of those efficiencies roughly equals to the total number of molecules (counted through the sample thickness) per λ 2 area (where λ is the wavelength of ...

WebThe measured incoherent scattering from hydrogen, for example, can be considerably larger (by more than 20%) than its bound value. For example, the incoherent scattering cross section of H 2 O is The macroscopic incoherent cross section calculated above includes no information about the structure of the material. WebSince the scattered x-ray photon has less energy, it, therefore, has a longer wavelength than the incident photon. The event is also known as incoherent scattering because the photon energy change resulting from an interaction is not always orderly and consistent.
