Small-Angle Neutron Scattering and Solvent Diffusion

3 Small-Angle Neutron Scattering and Solvent Diffusion 

Because of the similarities in wavelengths of X-rays and neutrons used in scattering experiments, the sizes of structures accessible to X-rays and neutron are similar. In polymeric materials, the substitution of deuterium for hydrogen in a structure dramatically changes its neutron scattering pattern, while the X-ray scattering remains unchanged because the
