of the scattering angle.
In SANS one measures the intensity of neutron scattered through small angles, usually less than 1 degree. Using Van Hove scattering equation
b = scattering length density, r = is the location of individual scatterer
Is a function of neutron energy and neutron momentum.
The Intensity is basically a measure of the number of neutrons scattered per second by the sample into a unit solid angle in a given direction, Having finalenergies E that lie between Ef and Ef + dEf
with research nuclear reactors. No home version of this technique.
