Incoherent scattering function

WebApr 23, 2016 · The table shows that the incoherent scattering cross-section of 1 H is 2–3 orders of magnitude higher than those of typical structural metals Zr, Fe, and Al. Of the metals, Ti is one of strongest incoherent neutron scatterers, but its incoherent scattering cross section is still about 30 times smaller than that of 1 H. WebApr 23, 2016 · Incoherent inelastic scattering can be applied to isolated hydrogens—where the protons can be modelled as in an isolated potential well formed by the surrounding atoms. At higher concentrations, the effect of H–H interactions and the role of hydrogen vibrational density of states are described. Ab initio theory becomes important in this case.

WebThe scattering signal is dominated by the corresponding contribution, which represents the (average) self-correlation function (in time) of the protons. For NSE spin incoherent scattering has the disadvantage that it flips the neutron spins during scattering with a probability of 2/3.
