Incoherent scattering of x-rays

WebNov 10, 2024 · “In the case of X-rays, incoherent scattering usually predominates, for example when fluorescent light is produced by photon absorption followed by photon emission,” explains Anton Classen from FAU, who is the principal author of a recent paper in the journal Physical Review Letters where the method was first presented theoretically ... WebThe intensity at low q ($0.01 Å À1) varied as a quadratic function of P H and indicated a minimum value at P H = 30%, which can be explained by the scattering contrast between SP and SBR. The scattering intensity at high q ($0.3 Å À1 ) decreased with increasing P H , which is attributed to the incoherent scattering from hydrogen.
