Small angle scattering of x-rays
Webb23 mars 2016 · Grazing-incidence small angle X-ray scattering Incident X-ray beam goes into the sample surface at a very shallow angle α i (normally less than 1°). Scattering is measured with a two-dimensional detector as a function of the exit angle α f (out-of-plane angle) and the in-plane angle 2 Θ. WebbThere are other notable differences between x-rays and neutrons employed small angle scattering. Most notably, Neutrons and x-rays of the same wavelength will have extremely different energies. For example, a neutron with a De Broglie wavelength of 0.15nm will have an energy of 36.4 meV while an x-ray with 0.15nm wavelength has an energy of 8.2 ...
